D. remains the same
Answers
Answer 1
Answer:
if i'm not mistaken the answer is A
Answer 2
The new acceleration will be increase by the factor of 2. Hence, option (A) is correct.
Given data:
The mass of body is, m = 40 kg.
We can use the Newton's second law to obtain the result of given problem. As per the Newton's second law, "The force applied by the given object is equal to the product of mass of object and the magnitude of acceleration of object". Then the expression is,
F = ma
a = F/m .....................................................................(1)
Here,
F is the force.
m is the mass.
a is the acceleration.
if the force acting in the mass of body of 40 kg is doubled. Then new acceleration will be,
F' = ma'
(2F) = ma'
2(F/m) = a'
From equation (1) we get,
a' = 2a
Thus, we can conclude that the new acceleration will be increase by the factor of 2. Hence, option (A) is correct.

I NEED HELP PLEASE, THANKS! :) Why is it a good idea to touch a metal pole, or similar conductor, before filling up a car with gas?
Answers
Answer:
While filling up the gas, a static discharge can take place which is really dangerous for us. It can even ignite a fire at the gas station. Touching the metal pole or any conductor will pass all of the charge into the Earth and thus we'll keep safe.
Answer:
It is a good idea to touch a metal pole or similar conductor before filling up a car with gas because it will discharge any static electricity on you, making it safer for everyone.
