Answer:
deposition, sublimation
Explanation:
The changes of state occur between solids and gases during deposition and sublimation. The second and fifth option are correct.
What is sublimation?The conversion of solid to gas and gas to solid directly, as in case of solid ice made of carbon di oxide.
The change of state means changing the phase of the matter with the change in temperature and pressure of the surrounding.
The vaporization change liquid to gas or solid to liquid and vice versa. Freezing is converting liquid to solid. Melting is converting from solid to liquid.
The rest phenomenon are deposition and sublimation in which phase change between solid and gas.
Thus, second and fifth option are correct.

Explanation:
A 950 kg truck accelerates from rest to 15 m/s in 2.3 seconds as it drives down a rough road. If the forward force of the engine is 7000 newtons, determine the force of friction between the tires and the road. 804 N 6,196 N 7,250 N 14,250 N
Answer:
804 N
Explanation:
We are given;
Mass; m = 950 kg
Initial velocity; u = 0 m/s
Final velocity; v = 15 m/s
Time; t = 2.3 s
Engine force; F_e = 7000 N
From Newton's first equation of motion;
v = u + at
15 = 0 + 2.3a
a = 15/2.3
a = 6.5217 m/s²
From Newton's second law of motion and since friction always opposes motion, we have;
F_e - F_f = ma
Where F_f is frictional force.
Thus;
F_f = F_e - ma
F_f = 7000 - (950 × 6.5217)
F_f ≈ 804 N

A 3kg ball is swung on the end of a 1m long string that is twirled with a speed of 3.2 m/s. What is the centripetal acceleration acting on the ball?
Answer:
The centripetal acceleration acting on the ball is 10.24 m/s²
Explanation:
Given;
mass of the ball, m = 3 kg
radius of the swing arm, r = 1 m
speed of the ball, v = 3.2 m/s
centripetal acceleration is given by;
a = v² / r
a = (3.2)² / 1
a = 10.24 m/s²
Therefore, the centripetal acceleration acting on the ball is 10.24 m/s²
Question 2 How can an induced magnet be made stronger? adding more secondary coils O adding more induction O adding more primary coils
Answer: adding a secondary coils
Explanation:
You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil.
Induced magnet be made stronger,by adding more secondary coils.
Increasing the magnetic field applied to the magnetizable material in turn makes its own magnetic field stronger. Similarly, wrapping with thicker wire has the same effect, but by increasing the current. Like a widening river, a thicker conductor allows more current through.
What is secondary coil ?"Coil such that current is induced in it by passing a current through the primary coil. secondary winding, secondary. coil - reactor consisting of a spiral of insulated wire that introduces inductance into a circuit."
What is magnetic field ?"A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field."

A farmer is walking through a field at a velocity of +0.5 meters per second (m/s) relative to the ground. At the same time, he is throwing seeds in front of him at a velocity of +2.1 m/s relative to himself. What is the velocity of the seeds relative to the ground as they travel through the air?
Answer:
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.
Explanation:
From Physics, we know that the absolute velocity of the seeds ([tex]v_{S}[/tex]) is the sum of the absolute velocity of the farmer ([tex]v_{F}[/tex]) and the velocity of the seeds relative to the farmer ([tex]v_{S/F}[/tex]), all measured in meters per second. That is:
[tex]v_{S} = v_{F}+v_{S/F}[/tex] (1)
If we know that [tex]v_{F} = 0.5\,\frac{m}{s}[/tex] and [tex]v_{S/F} = 2.1\,\frac{m}{s}[/tex], then the velocity of the seeds relative to the ground is:
[tex]v_{S} =0.5\,\frac{m}{s} + 2.1\,\frac{m}{s}[/tex]
[tex]v_{S} = 2.6\,\frac{m}{s}[/tex]
The velocity of the seeds relative to the ground as they travel through the air is 2.6 meters per second.

An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second squared in the direction of its motion for a distance fof 5 meters. What is the final speed of the object
Answer:
6 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 4 m/s
Acceleration (a) = 2 m/s²
Distance (s) = 5 m
Final velocity (v) =?
The final velocity of the object can obtained as shown below:
v² = u² + 2as
v² = 4² + (2 × 2 × 5)
v² = 16 + 20
v² = 36
Take the square root of both side.
v = √36
v = 6 m/s
Therefore, the final speed of the object is 6 m/s.
The final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.
Given the data in the question;
Initial speed; [tex]u = 4.0m/s[/tex]Acceleration; [tex]a = 2.0m/s^2[/tex]Distance; [tex]s = 5m[/tex]Final speed; [tex]v = \ ?[/tex]
To determine the final speed of the object, we use the third equation of motion:
[tex]v^2 = u^2 + 2as[/tex]
Where v is the final speed or velocity, u is the initial velocity, a is the acceleration and s is the distance covered.
We substitute our given values into the equation
[tex]v^2 = [(4.0m/s)^2] + [ 2\ *\ 2.0m/s^2\ *\ 5m ]\\\\v^2 = 16m^2/s^2 + 20m^2/s^2\\\\v^2 = 36m^2/s^2\\\\v = \sqrt{36m^2/s^2} \\\\v = 6m/s[/tex]
Therefore, the final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.

A soccer ball is kicked at an angle of 40 degrees with an initial velocity of
14 m/s. What is the horizontal velocity in m/s? (Do not state units, and give
answers to the hundredths place.) *
Answer:
[tex]v_x=10.72\ m/s[/tex]
Explanation:
Projectile Motion
It's the type of motion that experiences an object launched near the Earth's surface and moves along a curved path exclusively under the action of gravity.
Being vo the initial speed of the object, and θ the initial launch angle, the two components of the velocity are given by:
[tex]v_x=v_o\cos\theta[/tex]
[tex]v_y=v_o\sin\theta-g.t[/tex]
The soccer ball is kicked at an angle of 40° with an initial speed of vo=14 m/s.
The horizontal component is:
[tex]v_x=14\cos 40^\circ[/tex]
Calculating:
[tex]v_x=14\cdot 0.766[/tex]
[tex]\mathbf{v_x=10.72\ m/s}[/tex]

How much kinetic energy does a 2 kg book falling out of the backpack with a velocity of 4 m/s have?
Answer:
E = 16 J
Explanation:
Given that,
Mass of a book, m = 2 kg
Velocity of the book from the backpack, v = 4 m/s
We need to find the kinetic energy of the book falling out of the backpack. Due to the motion of the object, kinetic energy is possessed by it. It can be given by :
[tex]E=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 2\ kg\times (4\ m/s)^2\\\\=16\ J[/tex]
So, the kinetic energy of the book is 16 J.

Explanation:
1. If a worker has come into contact with electricity the worker may not be able to remove themselves from the electrical source. The human body is a good conductor of electricity. If you touch a person while they are in contact with the electrical source, the electricity will flow through your body causing electrical shock. Firstly attempt to turn off the source of the electricity (disconnect). If the electrical source can not readily and safely be turned off, use a non-conducting object, such as a fibreglass object or a wooden pole, to remove the person from the electrical source.
2. C- Electrical energy.The term electrical activity means that the food itself has the power to generate electric energy that persists some period of time. This work presents a purely renewable energy as energy comes. the zinc reacts with food tissue.
