Newton's Second Law of Motion states, “The force acting on an object is equal to the mass of that object times its acceleration.” We calculate as follows:
F = ma
At the moon,
104 N = m(1.61 m/s^2)
m = 64.60 kg
Mass will still be the same when on earth since mass is conserved.
At earth,
F=ma
F = 64.60 kg (9.8 m/s^2)
F = 633.04 N <----ANSWER
Answer:
44 m
Explanation:
Given:
v₀ = 4.0 m/s
v = 18 m/s
t = 4.0 s
Find: Δx
Displacement is the average velocity times time:
Δx = ½ (v + v₀) t
Δx = ½ (18 m/s + 4.0 m/s) (4.0 s)
Δx = 44 m
Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.
Answer:
25%
Explanation:
If there is 20% scrap, then
80% of (production + scrap) = 72 pcs/hr
Now,
The percent increase in labor productivity is, .
Or it can be written as 25% of which would give 80 pieces per hour.
