4 0

Answer In the field of physics, tension is called the force that is exerted by the action of a cable, rope, chain or other similar solid object. ... Since tension is a magnitude of force, it is measured in newtons and is always measured in a direction parallel to the chord on which it is applied.

Describe how the gas particles inside the balloon exert pressure on the balloon

Ostrovityanka [42]

as you pump more gas into the balloon, the particles become more packed, in an attempt to gain more room, the particles push on the walls of the balloon, therefore, making it expand.

Which is true concerning the acceleration due to Earth's gravity (ge) ? It decreases with increasing altitude. B. It is differe

klasskru [66]

Answer:

Option A decreases with increase in altitude

Explanation:

This can be explained as the value of gravitational acceleration, 'g' is not same everywhere.

It has its maximum value at poles of the Earth and minimum on its equator.

Thus a person will weigh more at poles than equator.

This variation is in accordance to:

$g = \frac{GM_{E}}{radius^{2}}$

Thus the gravitational acceleration changes as inverse square of the Radius of the Earth.

Thus as we move away from the Earth's center, gravitational acceleration, g decreases.

Vector A→, having magnitude 2.5m, pointing 37∘ south of east and vector B→ having magnitude 3.5m, pointing 20∘ north of east are

ahrayia [7]

Answer:

Magnitude of the resultant vector is R = 6.81 m

Explanation:

Given :

Vector A having magnitude of 2.5 m

Vector A having direction 37 degree south of east.

Vector B having magnitude of 3.5 m

Vector B having direction 20 degree north of east.

Therefore, the angle between the two vectors is, θ = 37+20 = 57 degree

So, the resultant of the two vectors are given by

$R = \sqrt{A^2+B^2+2AB \cos \theta}$

$R = \sqrt{2.5^2+3.5^2+2(2.5)(3.5) \cos 57}$

$R = \sqrt{6.25+12.25+17.5 \times 0.54}$

$R = \sqrt{46.45}$

R = 6.81 m
