Explanation:
weight=mass*gravity
w=mg
first change 220g to kg like this
1kg=1000g
?=220g
1kg*220g/1000kg=220/1000g
mass =0.22kg
now we can continue
w=0.22kg*10m/s^2 or w=0.22kg*10N/kg
=2.2N =2.2N
hope it helps you

The value of V is 640 km/hr.
<h3>What is Average velocity?</h3>
Average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
To calculate the value of V from the question, we use the formula below.
- V' = (V+U)/2............ Equation 1
Making V the subject of the equation
- V = 2V'-U.............. Equation 2
From the question,
⇒ Given:
- V' = 520 km/hr
- U = 400 km/hr
Substitute these values into equation 2
- V = (520×2)-400
- V = 640 km/hr
Hence, the value of V is 640 km/hr.

In order to change the frictional force between two solid surfaces, it can be changed by shorter distances and by the amount of weight it has or the amount of force that is pushing that object to go however distance it can.
Answer:
In helium
Explanation:
Since the units are the same, the value should only be considered.
