I assume it is directed 30 degrees above the positive x-axis. F = 50 pounds F_x = 50 cos(30) pounds = 43.3 pounds F_y = 50 sin(30) = 25 pounds Let i and j be unit vectors along the x and y axes, respectively. Then F = F_x i + F_y j = (43.3 i + 25 j) pounds
Answer:
17.284 rad/s^2
Explanation:
F = 337 N
R = 0.398 m
M = 98 kg
let the angular acceleration is α
torque = I x α = F x R
Where I is the moment of inertia
I = 1/2 MR^2 = 0.5 x 98 x 0.398 x 0.398 = 7.76 kg m^2
So,
7.76 x α = 337 x 0.398
α = 17.284 rad/s^2
Evaporation because the water from the pond will evaporate and transform into a field. To evaporate is when water molecules go up and there is no more water.
Answer:
B
Explanation:
When you lift something you are applying Force and Movement.
The two things we use in Work formula.
The other options you don´t have any movement happening.
Answer :
(a)
(b)
Explanation :
As are given:
1 inch = 2.54 cm
(a) Now we have to convert the number of kilometers in 1.00 mile.
Conversions used:
1 mile = 5280 ft
1 ft = 12 inch
1 inch = 2.54 cm
1 cm = 10⁻⁵ km
Thus,
(b) Now we have to convert the number of feet in 1.00 km.
