Answer:
Decrease occur in kinetic energy.
Explanation:
The kinetic energy decreases when the the Bob swings reaches to the maximum height because the motion of the bob slower down. At maximum height, the kinetic energy decreases whereas the value of potential energy is the highest. The main reason of higher potential energy is that it depends on height of an object while on the other hand, kinetic energy depends on the motion of an object so that's why the value of kinetic energy decreases and potential energy increases at maximum height of the bob.
Given :
- Acceleration (a) = 3.7 m/s²
weight is equal to :
Weight of the object is 0.37 Newtons ~
Correct choice is B
True, all motions are related to inclined planes.
Answer:
Rain jackets are coated in durable water-repellant (DWR) finish, a hydrophobic glaze that allows the coats to be breathable, yet waterproof. It lets water vapor—like sweat—out, but keeps rain from getting in. ... Without a DWR, the raincoat is just a coat. So, you'll need to recoat it.

This is according to the web
Answer:
<u>35.57 x 10²¹ N</u>
Explanation:
m(s) = 2 x 10³⁰ kg
m(e) = 6 x 10²⁴ kg
d = 1.5 x 10¹¹
G = 6.67 x 10⁻¹¹
F = Gm1m2/d²
= 6.67 x 10⁻¹¹ x 2 x 10³⁰ x 6 x 10²⁴ / 2.25 x 10²²
= 80.04 x 10⁴³ / 2.25 x 10²²
= <u>35.57 x 10²¹ N</u>
