Answer:
im 90% sure its C
bare in mind im only 90% so i suggest you wait for someone else to give their answer before you mark yours.
Answer:
V = 5.55 volts
Explanation:
Given that,
Current, I = 3.7 A
Resistance, R = 1.5 ohms
We need to find the voltage of the circuit. Let V is the voltage. We can find it using Ohm's law as follows :
V = IR
Substituting all the values, we get :
So, the voltage of the circuit is 5.55 V,
Answer:
Explanation:
From the given information:
the car's momentum = momentum of the truck
∴
(a) 816 kg × v = 2650 kg × 16.0 km/h
v = (2650 kg × 16.0 km/h) / 816 kg
v = 51.96 km/hr
(b) 816 kg × v = 9080 kg × 16.0 km/h
v = (9080 kg × 16.0 km/h) / 816 kg
v = 178.04 km/hr
This is how far I got:
put equation 3. into 1. together with h = 5:
4.
when I double m₁ the ratio becomes:
5.
when I put these to ratios back into equation nr 1 and nr2, I find the ratio:
and new v₁ = 2.95
I'm not sure this is correct.
