Newton's first law of motion is also known as the law of inertia. Newton's first law applies whether the object is in motion or not.

Objects do not change motion unless a force is applied. The second law states that the force on an object is equal to its mass times its acceleration. The third law states that when two objects interact, forces of equal magnitude and opposite directions are applied to each other. The law of motion shown in the picture is Newton's first law of motion.

According to Newton's first law of motion, a person at rest does not change motion until some pressure is applied. Newton's first law of motion describes how inertia affects moving and stationary bodies. Newton's first law states that an object will either remain stationary or move in a straight line with constant velocity unless an unbalanced force acts on it. Another name for Newton's second law is the law of force and acceleration.

A golf ball shifting ahead with 1 unit of momentum moves and bounces backward off a heavy bowling ball this is initially at relaxation and free to move. The bowling ball is ready in movement with a momentum of extra than 1 unit.

The bullet's mass is less than the gun's mass so the bullet's pace is greater than the gun's cringe speed. also, kinetic power is inversely proportional to mass. whilst a bullet is fired from a weapon, the weapon kicks within the opposite route. The motive for this is the pressure on the ball referred to as reaction.

Because the mass of the golf ball is greater than the mass of the bullet, the weapon recoils tons slower than the bullet's actions forward. A bowling ball this is desk-bound or transferred in a bowling alley does no gravitational work due to the fact gravity acts perpendicular to the surface. in step with Newton's third regulation of motion, each action has an equal and opposite reaction. when a gun fires a bullet it applies a force to the bullet that propels it forward.

Thermal system is used on some electric and hybrid vehicles to cool the power electronics and charger modules.

What is thermal system?

An isolated system has no interaction with the rest of the physical universe, a closed system can only exchange heat and work, and an open system can also exchange mass. In thermodynamics, a system is the portion of the physical universe that the observer chooses to analyse separately from the rest.

A thermal system, on the other hand, is a complex assembly of coupled components, some of which are thermal, that exhibits a common structured behavior  for instance, a refrigerator consists of pipes, a compressor, an electric motor, heat exchangers, valves, insulation, a casing, doors, a lamp, and other components that interact to achieve the internal goal of producing cold.

The interior space or the refrigerant are thermodynamic systems, whereas a refrigerator is a thermal system. While large thermal systems, like a refrigerated store, are constructed on the job site, small thermal systems, like a refrigerator, typically come fully installed from the manufacturer (although a straightforward split-air-conditioning system needs installation). Thermal systems often require services such as fuel supply, flue stack, water intake and exit, air intake and exit, and electrical supply (for power or at least for control).

Ice is the solid state of water - think about ice cubes you'd use to cool a soda, they are in solid state.

Water at room temperature is always liquid - remember that 'room temperature' is about 25°C.

It is FALSE that the proportionality dependence of the current (i) through any conductor to the voltage (v) across it and its resistance (r) is true for all conductors regardless of temperature.

When the conductors have a higher temperature, the molecules in the conductor will be more crowded and the result is the resistance of the conductor will rise. Hence, the current flowing through the conductor will decrease in the same voltage.

In the lower temperature, the resistance of the conductor will decrease and lead to more current flowing through the conductor in the same voltage.

Thus, the conductor temperature has an effect on its resistance.

The particle with a mass of 3m should be to the left of the third mass, and the particle with a mass of m should be to the right.

F = GMm/r² So that the net gravitational force exerted on M by the two masses is exactly zero, we must now determine where to place a third object of mass M.

Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. It is obvious that the gravitational force directly relates to the masses of the two interacting objects; larger, more massive objects will pull apart with a stronger gravitational force.

The comparison between the distance traveled by the bullet compared with the distance traveled by the rifle at the same time shows that the bullet travels faster than the rifle due to greater acceleration.

Newtown's third law of motion states that for every action there is a reaction having equal magnitude but opposite direction.

In the case of bullet and rifle, both experience the same amount of force that is equal in magnitude but opposite in direction.

In physics, mass and acceleration have an indirect relation with each other i.e a = F/m. More mass means less acceleration and vice versa.

A rifle has a smaller amount of acceleration than a bullet. It is because the mass of the rifle is greater than the bullet therefore it covers less distance a s compare to a bullet having less mass and greater acceleration and thus travels faster.

The normal force is less than the 10 N

Since we are given a box weight that is  10 N  tilted at 45⁰, so the formula we refer  from the figure to for calculating the normal force is:

N=mg⋅cos θ , where mg is the weight of the  box and θ is the angle at which the box is shifted.

The flatter the incline to be,  the normal force becomes greater. The littler an angle gets to be making the greater the esteem of cosine gets to be, and along these lines the greater the normal force becomes.

So, we get that the normal force will be

The speed of the shoot is 79.8 m/s.

The angle of projection of the cannonball is 90 degrees.

The time of motion of the cannonball is 16.3 seconds.

The speed of the shoot is obtained by applying the following kinematic equation.

v² = u² - 2gh

where;

at maximum height, the final velocity = 0

0 = u² - 2gh

u² = 2gh

u = √2gh

u = √(2 x 9.8 x 325)

u = 79.8 m/s

The angle of projection of the cannonball is calculated as follows;

h = (u²sin²θ)/2g

u²sin²θ = 2gh

sin²θ = (2gh) / (u²)

sinθ = √[(2gh) / (u²)]

sinθ = √[(2 x 9.8 x 325 ) / (79.8²)]

sinθ  = 1

The ratio of distance to time is referred to as the speed of an object. It is a scalar quantity with the SI unit of meters per second (m/s).

The given values according to the question are :

Height, h = 325 m

Final velocity, v = 0 m/s

The acceleration due to gravity, g = 9.8 m/s²

Use the formula and substitute the values,

v² = u² - 2gh

0 = u² - 2gh

u² = 2gh

[tex]u = \sqrt{2gh}[/tex]

u = √(2 × 9.8 × 325)

u = 79.8 m/s.

Now, calculate the angle of projection of the cannonball :

h = (u² sin²θ)/gh  

u² sin²θ = 2 gh

sin θ =[tex]\sqrt{(2gh)/u^2}[/tex]

sin θ = [tex]\sqrt{2(9.8*325)/(79.8)^2}[/tex]

sin θ = 1

θ = arc sin(1)

θ = 90°

On the Moon, gravity pulls less on objects so they weigh less. For example, a rock that weighs 1 pound weighs less on Earth than it does on the Moon. Weight is the result of the law of universal gravitation. Any two objects are attracted to each other by their masses with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

The mass remains the same and the weight decreases on the moon. When flying to the moon the gravitational acceleration is less than the gravitational acceleration.
