Answer:
1 joule of energy per second :)
Explanation:
Answer:
RT = 35 Ohms
Explanation:
Let the three resistors be R1, R2 and R3 respectively.
Given the following data;
R1 = 14 Ohms
R2 = 12 Ohms
R3 = 9 Ohms
To find the total resistance, RT;
Since all the resistors are connected in series, the total resistance is equal to the sum of all three resistance of the resistors.
RT = R1 + R2 + R3
Substituting into the equation, we have
RT = 14 + 12 + 9
RT = 35 Ohms.
Therefore, the total resistance of the circuit is 35 Ohms.
Answer:
A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. The potential energy decreases as the kinetic energy increases. The potential energy decreases as the kinetic energy decreases.
Hi there!
We can use the following:
W = ΔKE = F · d
Find the work done on the cart:
W = 200 · 10 = 2000 J
Now, this is equal to the change in kinetic energy of the object. Its initial kinetic energy is 0 J since it starts from rest, so:
2000J = KEf - KEi
KE is given as:
2000J = 1/2(55)v²
4000 = 55v²
√(4000/55) = 8.53 m/s
