Mars: 0.38
weight = mass x surface gravity
multiplying your weight on Earth by the number above will give you your weight on the surface of Mars
If you weigh 150 pounds (68 kg.) on Earth, you would weigh 57 lbs. (26 kg.) on Mars
Answer:
It increases to three times its original value. Given the same radius of wire and other constant property. current is directly proportional to the magnetic field.
B1=B2
MoI1/2pir=MoI2/2pir; cancel the same values on both sides
B2/B1=6/2 =3
Explanation:
A because of the resistors are four in this options first option is multiplied by 4
Answer:
Work done, W = 0 J
Explanation:
It is given that,
Weight of the bucket, W = F = 35 N
It is lifted vertically 3 m and then returned to its original position. We need to find the work gravity do on the bucket during this process.
Work done when the bucket is lifted vertically, W₁ = -mgh
Work done when the bucket returned to its original position, W₂ = +mgh
Net work done, W = W₁ + W₂
W = 0 J
So, the work done on the bucket is zero. Hence, this is the required solution.
Answer:
Since the net force is to the right (in the direction of the applied force), then the applied force must be greater than the friction force. The friction force can be determined using an understanding of net force as the vector sum of all the forces.
