A cell of e.m.f 1.5 v and internal resistance 2.5 ohm is connected in series with an ammeter of resistance 0.5 ohm and a resistor of resistance 7.0 ohm. Calculate the current in the circuit.
Answer:
The current in the circuit is 0.15 Ampere
Explanation:
The given parameters of the cell are;
The electromotive force (e.m.f.) of the cell, E = 1.5 V
The resistance of the cell, r = 2.5 ohm
The resistance of the ammeter = 0.5 ohm
The resistance of the resistor = 7.0 ohm
The formula for the e.m.f., E of a cell is given as follows;
e.m.f. E = I·(R + r)
Where;
I = The current in the circuit
R = The sum of the resistances in the circuit = 7.0 Ω + 0.5 Ω + 2.5 Ω = 10 Ω
Therefore, we have;
[tex]The \ current \ in \ the \ circuit, \ I = \dfrac{E}{R + r}[/tex]
Substituting the known values, gives;
[tex]I = \dfrac{1.5 \ V}{7 \ \Omega + 0.5 \ \Omega + 2.5 \ \Omega} = \dfrac{1.5 \ V}{10 \ \Omega} = 0.15 \ A[/tex]
The current in the circuit, I = 0.15 Ampere.
A car starts from rest and accelerates at a constant rate of 3.5 m/s2. What is the car’s velocity after the car has traveled 800 m?
Answer:
Attached is the answer
Explanation:
The car’s velocity after the car has traveled 800 m is 74.83 m/sec.
What is velocity?When an item is moving, its velocity is the rate at which its direction is changing as seen from a certain point of view and as measured by a specific unit of time.
Using equation of motion, initial velocity u = 0 and acceleration a = 3.5 unit and distance travelled is 800 m.
v² = u² + 2as
v² = 0 + 2*3.5*800
v² = 5600
v = 74.83 m/sec
The car’s velocity after the car has traveled 800 m is 74.83 m/sec.

a train has an initial velocity of 44m/s and an accelaration of _4m/s calculate its velocity
Complete question:
A train has an initial velocity of 44m/s and an acceleration of -4m/s². calculate its velocity after 10s ?
Answer:
the final velocity of the train is 4 m/s.
Explanation:
Given;
initial velocity of the train, u = 44 m/s
acceleration of the train, a = -4m/s² (the negative sign shows that the train is decelerating)
time of motion, t = 10 s
let the final velocity of the train = v
The final velocity of the train is calculated using the following kinematic equation;
v = u + at
v = 44 + (-4 x 10)
v = 44 - 40
v = 4 m/s
Therefore, the final velocity of the train is 4 m/s.

There is an apple with a mass of 14 kg that is attached to the tree 12
m above the ground (on earth). How much Gravitational Potential
Energy does the apple have? (Round to the nearest tenth)
Hint g= 9.8 (m/s^2)
*
Answer:
[tex]\boxed {\boxed {\sf 1646.4 \ J }}[/tex]
Explanation:
Gravitation potential energy can be found using this formula:
[tex]E_P=m*g*h[/tex]
where m is the mass, g is the gravtiational acceleration, and h is the height.
The mass of the apple is 14 kilograms and it is 12 meters above the ground. Since this is on Earth, the acceleration due to gravity is 9.8 m/s².
[tex]m= 14 \ kg \\g= 9.8 \ m/s^2 \\h= 12 \ m[/tex]
Substitute the values into the formula.
[tex]E_p= ( 14 \ kg )( 9.8 \ m/s^2)(12 \ m)[/tex]
Multiply.
[tex]E_p= (137.2 \ kg*m/s^2)(12 \ m )[/tex]
Multiply again.
[tex]E_P= 1646.4 \ kg*m^2/s^2[/tex]
1 kg*m²/s² is equal to 1 Joule. Our answer of 1646.4 kg*m²/s² is equal to 1646.4 Joules[tex]E_p=1646.4 \ J[/tex]
This is already rounded to the tenth place, so it's the final answer.
The apple has 1,646.4 Joules of gravitational potential energy.

A 5.0\, \text {kg}5.0kg5, point, 0, start text, k, g, end text box is at rest on a table. The static friction coefficient \mu_sμ
s
mu, start subscript, s, end subscript between the box and table is 0.500.500, point, 50, and the kinetic friction coefficient \mu_kμ
k
mu, start subscript, k, end subscript is 0.300.300, point, 30. Then, a 20\,\text N20N20, start text, N, end text horizontal force is applied to the box.
What is the best estimate of the magnitude of the box’s acceleration?
Answer:
25 N
Explanation:
When a force is applied to an object, for it to move it has to overcome the frictional force. The frictional force is perpendicular to the surface on which it acts. For an object at rest, it is acted upon by static friction, this friction must be overcome before the object can move, while a moving object is resisted by kinetic friction that prevents it from moving.
Since the box is at rest, it is acted upon by a static friction.
mass = 5 kg, acceleration due to gravity = 10 m/s², static friction coefficient = 0.5
Weight of the box = mass * acceleration due to gravity = 5 * 10 = 50 N
The applied horizontal force (F) is:
[tex]F=\mu_s*weight=0.5*50\\\\F=25\ N[/tex]

HELPPPPPPP !!!!!! PLS A 0.050 kg Truck moving right at 0.20 m/s collides with a toy race car weighing 0.015 kg initially at rest on a frictionless track. the truck keeps moving right at 0.15 m/s after Collision what is the final speed of the race car?
Answer:
[tex]v_f=0.15\:\mathrm{m/s}[/tex]
Explanation:
From the Law of Conservation of Momentum, we can write the following equation:
[tex]m_1v_1+m_2v_2=m_fv_f[/tex]
Because the toy car was initially at rest, [tex]m_2v_2=0[/tex].
Therefore, we can plug in given values and solve for [tex]v_f[/tex]:
[tex]m_1v_1=m_fv_f,\\0.050\cdot 0.20 = (0.050+0.015)v_f,\\v_f=\fbox{$0.15\:\mathrm{m/s}$}[/tex] (two significant figures).

What could you do to find the density of a fork, knife, and a spoon?
Answer:
Density is equal to mass divided by volume.
Explanation:
Density = mass / volume
or
p=m/v
Answer:
Use the formula D=m/v
Explanation: In order to find the volume for these objects, use a ruler and measure the length, width, and height. Proceed to multiply them all together, L*W*H. To find the mass of an object, I would say to use a triple beam balance. After finding both the mass and volume of you object, use the formula D = m/v and you'll get your answer.

A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. When these lenses are combined, they produce sharper images. Most of the eyeglass lenses use combinations of convex and concave lenses.
Two copper spheres are currently 0.5 meters apart. One sphere has a charge of
+3.4x10-4 C and the other has a charge of -5.6*10-4 C. What is the force between
the charged spheres? (k=8.89*10' Nm²/C2)
0 -6839.17 N
0 1200 N
0 5497.45 N
6839.17 N
Answer:
6839.17 N
Explanation:
From the question given above, the following information were obtained:
Distance apart (r) = 0.5 m
Charge 1 (q₁) = +3.4×10¯⁴ C
Charge 2 (q₂) = -5.6×10¯⁴ C
Electrical constant (K) = 8.98×10⁹ Nm²/C²
Force (F) =.?
F = Kq₁q₂ / r²
F = 8.98×10⁹ × 3.4×10¯⁴ × 5.6×10¯⁴ / 0.5²
F = 1709.792 / 0.25
F = 6839.17 N
Thus, the force of attraction between the two charged spheres is 6839.17 N
. Which Of The Following Will Produce Diffuse Reflection Of Light?
[A] Plane mirror and piece of paper
[B] Piece of paper and still water in lake
[C] Plane mirror and leather bag
[D] Piece of paper and leather bag
Answer:
A. Plane mirror and piece of paper
Explanation:
Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. An ideal diffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space adjacent to the surface.
Se necesita subir una carga de 500 kg (4900 N) a una altura de 1.5 m deslizándola sobre una rampa inclinada. ¿Qué longitud debe tener la rampa si sólo se puede aplicar una fuerza de 1633.33 N?
Answer:
4.22 m
Explanation:
Una rampa es una máquina que se utiliza para levantar un objeto con una fuerza menor a la que realmente necesitarías. Cuanto mayor sea la longitud de la rampa, menor será la magnitud de la fuerza necesaria para levantar el objeto.
Dado que:
altura de la rampa = 1.5 m, carga = 4900 N, fuerza aplicada = 1633.33 N.
La fórmula de la rampa se da como:
fuerza aplicada * longitud de la rampa = peso de la carga * altura de la rampa
1633.33 * longitud de la rampa = 4900 * 1.5
longitud de la rampa = 4900 * 1.5 / 1633.33
longitud de la rampa = 4.22 m

Answer:
Well it depends
Explanation:
If the runner leaves the base before
the ball is caught the defence cannot do anything exept
catch the ball if they catch the ball while he is still running he has to get back to the base before they could tag him or the base if they tag him or the base before he can get back to his base he is out if they did not catch the ball the runner can run as long as he wants just cant get taged the defence has to get the ball in as fast as possible to get the runner out.

Answer:
F=8.87 N
Explanation:
Coulomb's Law
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:
[tex]\displaystyle F=k\frac{q_1q_2}{d^2}[/tex]
Where:
[tex]k=9\cdot 10^9\ N.m^2/c^2[/tex]
q1, q2 = the objects' charge in coulomb
d= The distance between the objects in meters
Object 1 has a charge of
[tex]q_1=-2.3\cdot 10^{-6}\ c[/tex]
Object 2 has a charge of
[tex]q_2=-4.2\cdot 10^{-6}\ c[/tex]
They are separated by a distance of
d = 0.099 m
Calculate the force:
[tex]\displaystyle F=9\cdot 10^9\frac{2.3\cdot 10^{-6}*4.2\cdot 10^{-6}}{0.099^2}[/tex]
F=8.87 N
