Answer:

The tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called inertia. This is why, the first law of motion is also known as the law of inertia.

<em><u>Example</u></em><em><u>.: A ball at rest on the ground continues to be at rest unless someone kicks it or any external force acts on it.</u></em>

Explanation:

I hope this will help you buddy

Answer:

If I slap u forcely, then u will fly ... if I didn't u will stay at rest

Explanation:

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force

Dima020 [189]
Electric field strength = resistivity of copper x current density
where
p= 1.72 x 10^-8 <span>ohm meter
diameter = 2.05mm=.00205 m
current = 2.75 A
</span>get first the current density:
current density = current/ cross section area
find the cross section area
cross section area = pi.(d/2)^2;  
cross section = 3.3 006x10-6 m^2
substitute the values 
current density = 2.75A/3.3006x 10-6m^2
current density=35.55 x1 0^2 A/m^2
Electric field stregnth =1.72 x 10^-8 ohm meter x 35.55 x10^2 A/m^2
Electric field stregnth= 46.415 Volts/m

The electric field strength of copper is 46.415 V/m.

Light enters air from water. The angle of refraction will be A. less than the angle of incidence. B. greater than or equal to th
Rina8888 [55]

Answer:

E. greater than the angle of incidence.

Explanation:

Snell's law states that:

n_i sin \theta_i = n_r sin \theta_r (1)

where

n_i, n_r are the refractive index of the first and second medium

\theta_i, \theta_r are the angle of incidence and refraction, respectively

For light moving from water to air, we have:

n_i = 1.33 (index of refraction of water)

n_r = 1.00 (index of refraction of air)

Substituting into (1) and re-arranging the equation, we get

\sin \theta_r = \frac{n_i}{n_r} sin \theta_i = 1.33 sin \theta_i

which means that

\theta_r > \theta_i

so, the correct answer is

E. greater than the angle of incidence.

An object of mass m is moving down an inclined plane that makes an angle they a with the horizontal and has height h. Which of t
Lera25 [3.4K]
The answer should be B. According to the conservation of energy, the energy cannot be created nor destroyed, but it can be transformed. Since the object is moving down, that means its height is decreasing, causing the potential energy decreasing and the kinetic energy  increasing to fulfill the conservation law.
