A car travels with an average speed of 22 m/s.what is this speed in km/s
2 answers:
Answer:
22 m/s = 79.2 km/h
Explanation:
Given that,
The average speed of the car is 22 m/s. Here, we need to convert the speed to km/h. Firstly, we will see the following conversions as :
1 kilometres = 1000 meters
1 hour = 3600 seconds
To convert m/s to km/h we must use these coversions.
After solving the above expression, we get
22 m/s = 79.2 km/h
So, the car travel with a speed of 79.2 km/h. Hence, this is the required solution.

Answer:
A) Three hole punch and either a layered plastic or paper
B) Identify the lengths involved ,
Length of input arm / length of output arm = L1/ L2
Explanation:
<u>a) Materials involved includes :</u>
Three hole punch and either a layered plastic or paper
Identify the forces acting on the three-hole punch which are Input and output forces
Identify the points where they act
<u>B) procedures involved </u>
The mechanical advantage = output force / input force
step one: Identify the lengths involved
assuming no friction or relatively small friction \
mechanical advantage can be calculated as : Length of input arm / length of output arm = L1/ L2
