Answer:
5 J
Explanation:
F = spring force required to stretch the spring = 10 N
x = stretch in the spring = 1 m
k = spring constant of the spring
Spring force is given as
F = k x
Inserting the values
10 = k (1)
k = 10 N/m
W = work done in stretching the spring
Work done is given as
W = (0.5)k x²
Inserting the values
W = (0.5) (10) (1)²
W = 5 J
Answer:
Due to gravity on the earth but on moon there is 1/6th of the gravity than on earth. Since the acceleration of gravity Is lesser in moon and weight is constant, the weight of an object is lesser on the surface of the moon.
Explanation:
That would be crazy but the world already has certain pieces of matter on it
It is actually answer's 1, 2, and 3. I just did the assignment.
1) They use equations to predict future weather.
2) They collect data from weather stations.
3) They draw weather maps.
Answer:60 ohms
Explanation:
R1=30 ohms
R2=15 ohms
R3=15 ohms
Let total resistance be R
It is a series connection
R=R1 + R2 + R3
R=30 +15 + 15
R=60
Total resistance is 60 ohms
