D. Pearl Harbor

Explanation:

Answer:

The net force on the hockey puck is zero because it's acceleration is zero due to constant velocity.

The hockey will remain in it's uniform motion unless compelled by an external force.

Explanation:

[tex]from \: vector \: mechanics \\ a = \frac{dv}{dt} \\ but \: at \: constant \: velocity \\ \frac{dv}{dt} = 0 \\ hence : \: \: a = \frac{0}{dt} \\ a = 0[/tex]

Answer:

opaque

Explanation:

Materials such as wood, stone, and metals are opaque to visible light.

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.

How photosynthesis and cellular respiration are similar:

Photosynthesis is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration.

Answer:

Both nuclear fission and nuclear fusion produce energy from

matter

:D

Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.

The process by which two or more tiny nuclei unite to generate a bigger nucleus is known as a nuclear fusion reaction.

The more energy it takes to liberate an electron from a smaller atom. This is referred to as binding energy.

As a result, when two little nuclei fuse together, there is more binding energy than when two big nuclei fuse together.

For example, the fusion of two hydrogen atoms produces more energy than the fusion of one helium atom, and surplus energy is expelled into space upon binding.

Both nuclear fission and nuclear fusion produce energy from matter is the statement correctly comparing nuclear fission with nuclear fusion.

Hence option D is correct.

Explanation:

Answer:

The force on the wire increases

Explanation:

Since the force on the wire F = BILsinФ where B = magnetic field strength, I = current in wire, L= length of wire and Ф = angle between the magnetic field and the wire.

Given that the magnetic field and the wire are perpendicular, Ф = 90°

So, F = BILsin90° = BIL

Since B and L are constant, F ∝ I

So, if the current in the wire increases, the force on the wire also increases.

Answer:

velocity

Explanation:

velocity includes the direction taken by a person or object

The power used when a 100 N force is applied to move an object through a distance of 5 m at constant speed in 10 seconds is 50 W

We'll begin by calculating the energy. This can be obtained as follow:

Force (F) = 100 N

Distance (s) = 5 m

E = F × s

E = 100 × 5

Finally, we shall determine the power. This can be obtained as follow:

Energy (E) = 500 J

Time (t) = 10 s

[tex]P = \frac{E}{t}\\\\P = \frac{500}{10}[/tex]

Therefore, the power used in moving the object is 50 W.

Forces, Gravity, Friction, Direction, Acceleration.

The answers for the fill-in-the-blanks would be  Force, gravity friction

direction and acceleration respectively.

It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another,

There are a few ways that moving objects are impacted. Pushes and pulls, or force, have an impact on how an object moves.

The force of gravity drags items toward the Earth.

Friction is a force that causes objects to move more slowly or even come to a stop.

It also applies to an item that is reversing course or slowing down. Since acceleration is a change in velocity, it can also be a change in speed or direction.

Thus, Force, gravity friction direction, and acceleration are the answers respectively.

Answer:

Total distance = 2πr

Total displacement = 0

Explanation:

To Calculate the magnitude of distance and displacement of a body moving in a complete circle, we must come to these facts that:

The distance = circumference of the circle which is equal to the product of 2 ,pi and radius r

That is

Circumference = 2πr

Since velocity is changing and not constant, it is a vector quantity. Likewise displacement is a vector quantity.

The total displacement will be equal to zero.

Therefore, total distance is equal to the circumference of a circle while total displacement is equal to zero.

Answer:

Speed = 3 m/s

Explanation:

Given the following data;

Distance = 2700m

Time = 900 s

To find the speed;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting into the equation, we have;

[tex]Speed = \frac{2700}{900}[/tex]

Speed = 3 m/s
