find the angle between two forces of magnitude 27N and 30N if the magnitude of the resultant of the two force is 8N

Explanation:

Resultant of two forces, F = 8 N

It is required to find the angle between two forces. The resultant of two force is given by the :

is the angle between F₁ and F₂

So,

So, the angle between two forces is 165 degrees.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
