Answer:
gravityis an invisible force that pulls objects toward each other. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass .
Answer:
Mass of the body will be = 6 kg
Explanation:
Given:
Mass of an object = 6 kg
Acceleration due to gravity of the planet = 10 
To find the mass of the body on that planet.
Solution:
Mass of the body is defined as the total amount of matter contained in the body.
Thus, mass of a body will always remain constant irrespective of the acceleration due to gravity. This is because it is an independent quantity and does not vary with acceleration due to gravity.
<em>It is the weight of the body that changes with the change in the acceleration due to gravity as it is given by:</em>

where
represents mass of the body and
represents the accelration due to gravity.
Hence, the mass of the given body will remain = 6 kg.
Answer:
The average force is 1578.94 N.
Explanation:
Given that,
Mass of baseball = 150 g
Speed = 45 m/s
Speed of pitcher = 60 m/s
Time = 9.5 ms
We need to calculate the average force
Using formula of impulse

...(I)
....(II)
From equation (I) and (II)

Where, m = mass of baseball
= final velocity
= Initial velocity
= time
Put the value into the formula


Hence, The average force is 1578.94 N.
<span>Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide. When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person.

Answer:
x = 54.15 meters between the balloons horizontally.
Explanation:
Hence, vertical distance between balloons is 12.8 meters.
y= 61-48.2 = 12.2 m
A right-angle triangle is formed with,
angle θ = 13.3 degrees
opposite (y) = 12.8
adjacent (x) = ?

Now by putting the values in the above equation.


x = 54.15 meters between the balloons horizontally.
