Answer: both mass and velocity
Explanation:
Momentum is defined as the product of mass (m) and velocity (v) of a moving body. Hence, momentum is expressed as mv. The unit of momentum is kilograms metre per second (kgm/s).
For instance:
A bullet having a small mass of 0.01kg moving with a velocity of 10000m/s and a heavy ball of mass 100kg moving with a small speed of 1m/s have the same momentum.
Thus, both mass and velocity affect momentum.
Answer:
θ = cos^(-1) (-A/B)
Explanation:
The image of the reauktant forces A & B are missing, so i have attached it.
Now, from the attached image, we will see that;
Angle between A and B is θ
Also;
A = Bcos(180° − θ)
Now, in trigonometry, we know that;
cos(180° − θ) = -cosθ
Thus;
A = -Bcosθ
cosθ = -A/B
Thus;
θ = cos^(-1) (-A/B)
<h2>Answer:</h2>
<u>The correct option is</u><u> (C) its greater tensile strength </u>
<h2>Explanation:</h2>
Elasticity is the property of any material to return to its original shape when it is de-shaped. for example a spring comes to its original shape when it is stretched and then released. so the property that brings the spring back to its original form is called elasticity. On the other hand tensile strength is the maximum stress that a material can withstands before it breaks. Since polymers are also elastic so the greater tensile strength means greater elasticity.
