Answer:gravity is a force of attraction that acts between two masses separated by distance
Explanation:
Gravity is a force of attraction that acts between two masses separated by distance
Wave speed = wave length * frequency
It should be Coulomb’s Law.
F = K * (q1*q2)/(r^2)
Where K is (9*10^9)
q is the charges
r is the radius between them.
When working with these, also remember to break them into the x and y component forces if there are multiple and one is at a diagonal.
After doing that, add all X and Y together, then use a^2+b^2=c^2 to get the total magnitude.
Answer:
1.056 x 10⁷ lb-ft
Explanation:
v = Speed of the bike = 20 mph
t = time of travel = 2 h
d = distance traveled by cyclist
Distance traveled by cyclist is given as
d = v t
d = (20) (2)
d = 40 miles
We know that, 1 mile = 5280 ft
d = 40 (5280) ft
d = 211200 ft
F = force applied by cyclist = 50 lb
W = work done by cyclist
Work done by cyclist is given as
W = F d
W = (50) (211200)
W = 1.056 x 10⁷ lb-ft
