Answer:
Explanation:
From the question we are told that:
Height
Time
Generally the Newton's equation for Initial velocity upward is mathematically given by
Generally the velocity at elevation and depression occurs as ball arrives and passes through S=28
Generally the Newton's equation for time to reach initial velocity is mathematically given by
The needle has buoyancy and that means it won't sink. It also has a lot to do with the weight of the needle which is very little. The less weight there is the easier it will be to float.
Answer:
a
The pressure will increase
b
Explanation:
From the ideal gas law we have that
We see that the temperature varies directly with the pressure so if there is an increase in temperature that pressure will increase
The initial temperature is
The objective of this solution is to obtain the temperature of the gas where the pressure is tripled
Now from the above equation given that nR and V are constant we have that
=>
Let assume the initial pressure is
So tripling it will result to the pressure being
So
=>
=>
=>
Converting back to
=>
Answer:
Explanation:
Mass of the boy, m = 62 kg
Mass of the girl, m' = 46 kg
The acceleration of the girl toward the boy is,
The force acting on the girl is given by :
F' = 138 N
Let a is the magnitude of the acceleration of the boy toward the girl. Again using the second law of motion to find it as :
So, the the acceleration of the boy toward the girl is .
