murzikaleks [220]

As the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

<h3>What is a projectile?</h3>

A projectile is an object launched into space at an angle to the horizontal ground and allowed to fall freely under gravity.

The path of motion of a projectile is parabolic.

Examples of objects that are projectiles include:

A thrown banana
A kicked football
An arrow shot from a bow

Therefore, as the banana flies through space, up the red arrow showing its path of motion takes a curved or parabolic shape.

Two plastic bowling balls, 1 and 2, are rubbed with cloth until they each carry a uniformly distributed charge of magnitude 0.50

galben [10]

Answer:

The right solution is " $4.5\times 10^{-10} \ Cm$ ".

Explanation:

Given that,

q = 0.50 nC

d = 900 mm

As we know,

⇒ $P=qd$

By putting the values, we get

⇒ $=0.50\times 900$

⇒ $=(0.50\times 10^{-9})\times 0.9$

⇒ $=4.5\times 10^{-10} \ Cm$

A cart traveling at 0.3 m/s collides with stationary object. After the collision, the cart rebounds in the opposite direction. T

lesya [120]

Answer:

Impulse in the first collision is greater

Explanation:

u = Initial velocity of cart

v = Final velocity of cart

m = Mass of of cart

First collision

Impulse

$J=m(v-u)\\\Rightarrow J=m(0.3-(-0.3))\\\Rightarrow J=m(0.6)$

Second collision

Impulse

$J=m(v-u)\\\Rightarrow J=m(0-(-0.3))\\\Rightarrow J=m(0.3)$

Hence, the impulse in the first collision is greater than the second impact
