Answer:
your friend will wait for you for 2.2 minutes.
Explanation:
Given;
Distance of the journey, d = 50 km
your speed, v₁ = 88.5 km/h
your friends speed, v₂ = 94.5 km/h
The time taken before you reached the end of the trip;
The time taken before your friend reached the end of the trip;
The difference in time = (0.565 - 0.529) hour
= 0.036 hour
= 0.036 x 60 min
= 2.2 mins
Therefore, your friend will wait for you for 2.2 minutes.

Answer:
0.18 amperes
Explanation:
V = 9
R = 50 ohms
I = ?
Formula
V = I * R
Solution
9 = I * 50 Divide by 50. Switch
I = 9 / 50
I = 0.18 amperes.
If you know what a milliampere is then it is 180 ma which is very large for a 9 volt battery to handle
