Answer:
4m/s2
Explanation:
acceleration=v-u/t...v=12m/s,u=0m/s,t=3sec
a=12-0/3
=4m/s2
Answer:b.20.8L
Explanation:
Since pressure is constant we can use the equation V1/T1 = V2/T2
(20/250)=(x/260)
5200=250x
X=20.8
To maximize the power delivered to load, we should minimize the internal resistance which means option A is correct.
<h3>What is the relationship between the power and the internal resistance?</h3>
Power can be delivered to the internal resistance of a battery, but in a case whereby there is a decrease in the internal resistance will bring about the decrease in the lost power as well as the increase in the percentage of the power delivered to the device.
In this case, To maximize the power delivered to load, we should minimize the internal resistance
Therefore, Option A is correct.

You need to rearrange this equation to find mass so you would have the equation :
M = f/a
Input the numbers into the equation :
M = 56/7
M = 8
