Energy can generally be considered to be either kinetic energy or potential energy. Some specific forms of energy, such as electrical, magnetic, and gravitational energy, can operate in the space around objects and affect other objects that come near. In these examples,
Answer: The options are not given.
Here are the options.
A. energy is continuously created.
B. energy is continuously destroyed.
C. energy exists in a field.
D. all of these
The correct option is C.
Energy exists in a field.
Explanation:
Energy is the ability to do work or the property i.e force or power that is moved to an object so that it can perform work.
Energy exists in a field because a field is a region in which each area is affected by a force or power on an object . For example a paper clip placed on a magnetic field require a force or power to be able to attract or repel magnets.
An electric field surronds an electric charge when another particle is around it, it uses energy to either attract or repel the object e.t.c.
Therefore energy exists in field.

What is the coefficient of friction of an object with a weight of 300 N and a force of friction of 150 N?
1
0.75
.5
0
Answer:
0.5
Explanation:
Given parameters:
Weight of object = 300N
Force of friction = 150N
Unknown:
Coefficient of friction = ?
Solution:
Frictional force is a force that resists the motion of a body.
It is mathematically expressed as;
frictional force = uN
Where u is the coefficient of friction
N = Normal force = weight of the object
Now input the parameters and find u;
150 = u x 300
u = [tex]\frac{150}{300}[/tex] = 0.5
The coefficient of friction here is 0.5

How do the lights in a series circuit behave when one bulb burns out?
O The rest of the bulbs continue to shine at maximum brightness.
OThe rest of the bulbs continue to shine at a lower brightness.
OThe rest of the bulbs continue to shine at a higher brightness
OThe rest of the bulbs stop shining and shut off.
Answer:
D. The rest of the bulbs stop shining and shut off.
Explanation:
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off. Option D is correct.
What is an electric bulb?
An electric bulb is a gadget that uses electricity to create visible light. It is the most popular type of artificial lighting and is necessary for modern society.
The light bulb is connected to a switch in a parallel configuration. The switch is open, which means there will be a lot of resistance and no current will flow via this route.
Across the parallel connection, the battery would create the same potential difference. Because the current would not go via the open switch, it would instead flow through the light bulb, causing it to illuminate.
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off.
Hence, option D is correct.

You row a boat perpendicular to the shore of a river that flows at 3 m/s. The velocity of your boat is 4 m/s relative to the water. What is the velocity of your boat relative to the shore?
Answer:
The velocity vBW of the boat relative to the water is 4.0 m/s, directed perpendicular to the current, as in Figure 3.18.
Explanation:
The boat is perpendicular to the shore. Then the net velocity of the boat with respect to river is 5 m/s. The observer feels like the boat is moving slower than they appear actually.
What is relative velocity ?Relative velocity is velocity of an object measured with respect to other object which can be of stationary or moving with a speed. Thus speed relative to another object is called the relative velocity.
The relative velocity is what's the speed for an observer but it differs from actual velocity. Sometimes it may slower or faster depending on the object with which a we are relating the speed.
Given that the speed of the boat = 4 m/s
speed of river = 3 m/s.
Both are perpendicular and the net velocity of the boat is :
r = √(3² + 4²) = 5 m/s.
Hence, the velocity of the boat relative to the shore will be 5 m/s.

A car started its motion from rest and accelerated for 6 seconds, with the acceleration of 4 m/s2. Then it decelerated for 5 seconds, with the acceleration of -1.6 m/s2. What was the velocity of the car after 6+5 seconds?
Answer:
16 m/s
Explanation:
from the formula: a = velocity/time
you calculate the velocity in both cases (when time is 5 sec and 6 sec) by using the formula: velocity = a x time
v (5 sec) =24 m/s
v (6 sec) = - 8 m/s
then : add v (5 sec) to v (6 sec) and the result is 16 m/s
List out Units For: Acceleration
Unit for Acceleration is m/s² or ms raised to -2

how much force is needed to accelerate 300 kg at a rate of 4 m/s/s
Answer:
1200
Explanation:
Force = Mass x Acceleration
Answer:
[tex]\boxed {\tt 1,200 \ Newtons }[/tex]
Explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass is 300 kilograms.
The acceleration is 4 meters per second squared.
[tex]m= 300 \ kg\\a= 4 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 300 \ kg * 4 \ m/s^2[/tex]
Multiply.
[tex]F= 1200 \ kg * m/s^2[/tex]
1 Newton is equal to 1 kilograms meters per second squared, so our current answer of 1200 kg m/s² is equal to 1200 Newtons.
[tex]F= 1200 \ N[/tex]
The force needed is 1,200 Newtons.

Where would the net force acting on a charge placed in a system of like charges be zero?
Answer:

Why would the CPSC perform studies when other soap and detergent companies have already conducted research on the same products? The CPSC is the only organization that can test the safety of soaps and detergents. Studies conducted by any company that benefits financially are considered unreliable. Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company. Tests performed by the CPSC follow established scientific methods, but those performed by soap companies do not.
Answer: Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.
Explanation:
The function of Consumer Product Safety Commission is to make sure that the products which are used by consumers are safe and also make sure that companies meet the required and acceptable safety standards. The products that are seen to be harmful to the health of the consumers are banned.

A gold puck has a mass of 12 kg and a velocity of 5i – 4j m/s prior to a collision with a stationary blue puck whose mass is 18 kg. After an elastic collision, the blue puck has a velocity of 2i – 2j m/s. What is the velocity of the gold puck after the collision?
A. 2i –j m/s
B. 3i –j m/s
C. 2i – 2j m/s
D. 3i – 2j m/s
Answer:
Explanation:D
The velocity of the gold puck after the collision is equal to (2i - j) m/s. Therefore, option (A) is correct.
What is velocity?The rate at which a displacement of the body changes in relation to time is called its velocity. Velocity is a vector parameter with both magnitude and direction. S.I. unit of velocity can be represented as meter/second.
Given, the mass of the gold puck, m = 12 kg
The velocity of the gold puck before the collision, u = 5i – 4j m/s.
The mass of the stationary blue puck, M = 18 kg.
The velocity of it after the collision, V = 2i – 2j m/s.
We have to determine the velocity of the gold puck after the collision:
The total momentum of the system before the collision is equal to the total momentum of the system after the collision.
mu + M ×0 = mv + MV
v = u - MV/m
v = (5i – 4j) m/s - (2i – 2j)m/s × 18/12
v = (5i – 4j) m/s - (3i - 3j)
v = (2i - j) m/s.
Therefore, the velocity of the gold puck is (2i - j) m/s after the collision.
