Answer:
57908 N
Explanation:
Let's first convert Dumbo's mass into kg using the given relationship: 2.2 pounds =1 kg.
Then, 13000 lbs = 13000/2.2 kg = 5909 kg
Now, let's find the force of gravity on Dumbo at the surface of the earth, which would be in magnitude equal to the normal force that the Earth's surface applies on Dumbo.
F = m * a = 5909 kg * 9.8 m/s^2 = 57908 N
Answer:
Explanation:
Given that,
5J work is done by stretching a spring
e = 19cm = 0.19m
Assuming the spring is ideal, then we can apply Hooke's law
F = kx
To calculate k, we can apply the Workdone by a spring formula
W=∫F.dx
Since F=kx
W = ∫kx dx from x = 0 to x = 0.19
W = ½kx² from x = 0 to x = 0.19
W = ½k (0.19²-0²)
5 = ½k(0.0361-0)
5×2 = 0.0361k
Then, k = 10/0.0361
k = 277.008 N/m
The spring constant is 277.008N/m
Then, applying Hooke's law to find the applied force
F = kx
F = 277.008 × 0.19
F = 52.63 N
The applied force is 52.63N
D. because the statue has a new chemical called patina. It is no longer copper.
I am pretty sure the answer is C.
