Answer: 1.d) The acceleration of an object is always less than the acceleration due to gravity, g (9.81m/s^-2)

2.a)acceleration decreases

Explanation:

Newton's second law:

Newton's second law states that the acceleration of an object is defined by two variables which is the total force acting on the object and the mass of that object. The acceleration is directly proportional to the net force that is applied on an object and inversely proportional to the mass of that object.

When the force applied on an object is increased so does the acceleration of an object however if the mass increase the acceleration decreases.

This can be felt when you look at the truck which usually carry heavy loads they seem to drive slow due to the load hence their acceleration is decreased by the mass that these truck carry .

V125BC [204]

Answer:1.27

Explanation:

Given

incident angle i=36^{\circ}

refracted angle r=27.5^{\circ}

Suppose n_2 is the refractive index of material then using Snell's law we  can write

n_1\sin i=n_2\sin r

where n_1=refractive index of air

1\times \sin (36)=n_2\times \sin (27.5)

n_2=\dfrac{0.5877}{0.4617}

n_2=1.27

A ball is ejected to the right with an unknown horizontal velocity from the top of a pillar that is 50 meters in height. At the
dimulka [17.4K]

Answer:

15.67 m/s

Explanation:

The ball has a projectile motion, with a horizontal uniform motion with constant speed and a vertical accelerated motion with constant acceleration g=9.8 m/s^2 downward.

Let's consider the vertical motion only first: the vertical distance covered by the ball, which is S=50 m, is given by

S=\frac{1}{2}gt^2

where t is the time of the fall. Substituting S=50 m and re-arranging the equation, we can find t:

t=\sqrt{\frac{2S}{g}}=\sqrt{\frac{2(50 m)}{9.8 m/s^2}}=3.19 s

Now we now that the ball must cover a distance of 50 meters horizontally during this time, in order to fall inside the carriage; therefore, the velocity of the carriage should be:

v=\frac{d}{t}=\frac{50 m}{3.19 s}=15.67 m/s
