1. e) None of the above is necessarily true.
2.d) Without knowing the mass of the boat and the sack, we cannot tell.
Answer:
6 V
Explanation:
We can solve the problem by using Ohm's law:
where
V is the voltage in the circuit
R is the resistance
I is the current
In this problem, we know the current, 
, and the resistance, 
, therefore we can find the voltage in the circuit:
Answer:
Gravitational energy and kinetic energy
Answer:K.E=449598.5j
Explanation:
Kinetic energy of a moving car=1/2mv^2
Where m is the mass of the car
And V is the velocity of the car
K.E=1/2 ×1300×26.3^2
K.E=449598.5j
Answer:
I gonna give you the number so but you need to round 6.19047619048
Explanation:
- This is a speed formula so you would use the formula speed=distance/time
- You need to rearrange it to time=distance/speed
- So you need to divide 13m by 2.1 m/s
