Shawn is doing drills out on the field by pulling a tire behind him for 30 m. If Shawn is applying a net force of
1200 N to pull the tire, then how much work is Shawn doing?
Answer:
The work done by Shawn in moving the tire is 36,000 J
Explanation:
Given;
net force applied by Shawn , F = 1200 N
distance he moved the tire, d = 30 m
The work done by Shawn in moving the tire is calculated as;
W = Fd
Substitute the given values and solve for Work done;
W = 1200 x 30
W = 36,000 J
Therefore, the work done by Shawn in moving the tire is 36,000 J
They did a flu shot from McKinnon at 45° to the horizontal with an initial speed of 25 m/s and that is positioned at a horizontal distance of 50 m from the canyon from which it is shot how long does it take the daredevil to travel the 50 m horizontally
Answer:
The time taken for the daredevil to travel the 50 m horizontally is 2.83 s.
Explanation:
Given;
angle of projection, θ = 45°
initial speed of the projectile, u = 25 m/s
horizontal distance traveled by the projectile, x = 50 m
The time taken for the daredevil to travel the 50 m horizontally is calculated as;
[tex]t =\frac{X}{u_x}[/tex]
where;
[tex]u_x[/tex] is the horizontal component of the velocity = uCosθ
[tex]t =\frac{X}{u Cos \ \theta} \\\\t =\frac{50}{25 \times Cos(45)} \\\\t= \frac{50}{17.678} \\\\t = 2.83 \ s[/tex]
Therefore, the time taken for the daredevil to travel the 50 m horizontally is 2.83 s.

Which best explains why trees are considered a renewable resource? O They are useful to humans. O They can be replanted. 0 They provide a source of food. They are used to produce heat.
Answer:
They can be replanted.
Explanation:
Renewable sources can be found again and again, similar to how you can plant a tree again to receive food sources and heat production, which in turn is useful to humans.
When The trees are considered a renewable resource because They can be replanted. The correct option is 'B'.
What is a Renewable Resource?
When Renewable sources can be found, again and again, similar to how you can plant a tree again to receive food sources and also heat production, they are in turn useful to humans.
When the renewable resources are resources, generally naturally happening, they can replenish to the rate that they can return the used volume and also be swallowed.
A renewable resource will either produce itself naturally through automatic approaches to that resource or through human interaction and guidance.
Therefore, The correct option is 'B'.

How does static electricity apply to car
paint application?
Answer:
For electrostatic paint to be applied, the vehicle needs to be grounded and positively charged. This creates a magnetic attraction to the negatively charged paint. Due to this charge, when the paint leaves the nozzle, it is attracted to the vehicle's charge and will stick to it.

A 3.0 g bullet traveling at a speed of 400 m/s enters a tree and exits the other side with a speed of 200 m/s. Where did the bullet's lost KE go, and what was the energy transferred?
Answer:
1800J
Explanation:
Step one:
given data
mass of bullet m= 3g= 0.03kg
initial velocity u = 400m/s
final velocity v= 200 m/s
Step two:
1.The bullet's lost kinetic energy went inside the tree.
2. The energy transferred is computed as
= initial KE- KE final
Initial KE= 1/2mu^2
Initial KE= 1/2*0.03*400^2
Initial KE= 1/2*0.03*160000
Initial KE= 1/2*4800
Initial KE= 2400J
KE final= 1/2mv^2
KE final= 1/2*0.03*200^2
KE final= 1/2*0.03*40000
KE final= 1/2*1200
KE final= 600J
KE transferred = 2400-600
KE transferred= 1800J
A train is accelerating at a rate of 2.0 m/s/s. If it accelerates at this rate for 30
seconds, what is the change of velocity? *
Answer:
60m/s
Explanation:
Given parameters:
Acceleration = 2m/s²
Time = 30s
Unknown:
Change in velocity = ?
Solution:
Acceleration is the rate of change of velocity with time.
Mathematically;
Acceleration = [tex]\frac{Change in velocity }{Time }[/tex]
Now,
Change in velocity = Acceleration x time
So,
input the parameters and solve;
Change in velocity = 2 x 30 = 60m/s

2. Two projectiles thrown from the same point at angles 0,=60° and 02=30° with the horizontal,
attain the same height. What is the ratio of their initial velocities (Voi:Voz)?
Answer:
The answer is below
Explanation:
The maximum height (h) of a projectile with an initial velocity of u, acceleration due to gravity g and at an angle θ with the horizontal is given as:
[tex]h=\frac{u^2sin^2\theta}{2g}[/tex]
Given that the two projectile has the same height.
[tex]For\ the\ first\ projectile\ with\ an\ angle\ \60^0 \ with\ the\ horizontal\ and initial\ velocity\ u_1:\\\\h=\frac{u_1^2sin^260}{2g} =\frac{0.75u_1^2}{2g} \\\\For\ the\ second\ projectile\ with\ an\ angle\ \30 \ with\ the\ horizontal\ and initial\ velocity\ u_2:\\\\h=\frac{u_2^2sin^230}{2g} =\frac{0.25u_2^2}{2g}\\\\\frac{0.25u_2^2}{2g}=\frac{0.75u_1^2}{2g}\\\\0.25u_2^2=0.75u_1^2\\\\\frac{u_1^2}{u_2^2} =\frac{0.25}{0.75} \\\\\frac{u_1^2}{u_2^2}=\frac{1}{3} \\[/tex][tex]\\\frac{u_1}{u_2}=\sqrt\frac{1}{3}[/tex]

Is visible light a form of
radiation? Explain.
Answer:
Yes,in fact visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets', called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).
Explanation:
Between ball B and ball C, ball ____ has LESS potential energy because ___
a: c;its mass is greater
b: b;its mass is smaller
c: c; its mass is smaller
d: b;its mass is greater
Answer: b
Explanation:
Ec= (1/2)m × v^2
By the formula, you can see that the bigger the mass, the bigger the Cinetic Energy.
b: b; its mass is smaller
Between ball B and ball C, ball B has LESS potential energy because its mass is smaller.
A potential energy, stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched.
Potential energy is given by formula.
[tex]P.E= m*g*h[/tex]
Since, P.E is directly proportional to mass. Thus, the ball having smaller mass will have the less P.E.
Thus, option b is correct.

4. The electric force between electric charges is much larger than the
gravitational forces between charges. Why, then, is the gravitational force
between the Earth and the Moon much larger than the electric force between
them?*
A. The electric force is small in comparison because charges are VERY small but the
gravitational force has to do with the mass of the Earth and Moon.
B. The electric charge is actually greater and the question is false.
C. The phases of the Moon determine the amount of electric and gravitational force.
The electric force is small in comparison because charges are VERY small but the
gravitational force has to do with the mass of the Earth and Moon.
Write down the factors on which moment depends upon ?
Answer:
The size of a forceThe perpendicular distance from the pivot the line of action of forceExplanation:
Factors that affect the moment of a force are;
The size of a forceThe perpendicular distance from the pivot the line of action of forceThe magnitude of force applied is directly proportional to the moment of force in that for a perpendicular distance d, increased in force applied will result to a higher moment of force. When the perpendicular distance from the pivot is decreased while the force applied remains constant, the moment of force decreases.

A man standing on top of a 30 m tall building throws a brick downwards with a velocity of 12 m/s. Determine the speed of the brick just before it hits the ground.
Answer:
27.1m/s
Explanation:
Given parameters:
Height of the building = 30m
Initial velocity = 12m/s
Unknown:
Final velocity = ?
Solution:
We apply one of the kinematics equation to solve this problem:
v² = u² + 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
v² = 12² + (2 x 9.8 x 30)
v = 27.1m/s
