What would happen if the gravity on earth decreases by a small about? ​

Answers

Answer 1
Answer: If the gravity decreases on the earth, we will be weightless and pressure will be less exerting on us and we will be able fly
Answer 2
Answer:

a loss of gravity on earth would  stop pulling down the air,water and earth's atmosphere

ther would be a sudden and significant loss of air pressure

the lack of any forceful gravitational pull would turn humans

Without gravity, humans and other objects would become weightless.

a cannon ball is fired at 40 degrees with an initial velocity of 180 m/s. what is the maximum height reached by the cannonball?

Answers

A ball is fired with speed v = 180 m/s at an angle 40 degree

So here we can say the components of velocity is given as

v_(x) = 180 cos40 = 137.9 m/s

v_y = 180 sin40 = 115.7 m/s

now when ball will reach the maximum height its velocity in vertical direction will become zero

so here we can say

v_(fy) = 0

now using kinematics we will have

v_(fy)^2 - v_y^2 = 2 a d

0 - 115.7^2 = 2(-9.8)(H)

so maximum height is

H = 683 m

so it will reach at maximum height of 683 m

What has to happen for a feather and a ball to fall at the same rate?

Answers

Because the force of gravity is different for both of these objects, they will not fall at the same rate. To make both of these fall at the same rate, we need both to have the same mass so that the gravitational pull is equivalent also. 
They will NOT fall at the same late.
A ball will fall much faster than a feather. A feather tends to float down, much as a ball, it immediately drops. 

Why do automobiles rust more easily in wet climates than drier climates?

Answers

Wet climates obviously have more water than driers climates. Metals, when subject to water have the tendency to oxidize (rust). Therefore, if water is barely present in a climate, then oxidation is also least likely to occur.
