Answer:
option A
Explanation:
given,
For exerted by the worker = 245 N
angle made with horizontal = 55°
we need to calculate Force which is not used to move the crate = ?
Movement of crate is due to the horizontal component of the force.
Crate will not move due to vertical force acting on the it.
hence, worker's force not used to move the crate is equal to 200.69
The correct answer is option A
When you're dealing with quantities that produce very large or very small numbers in the units that you're using; like meters to Neptune, or kilograms in one Hydrogen atom.
Answer:
3.78 W
Explanation:
P = V x I
P = 5.4 x 0.14 = 0.756 W (One bulb)
Total power output : 5 x 0.756 = 3.78 W
Answer:
d = 84 m
Explanation:
As we know that when an object moves with uniform acceleration or deceleration then we can use equation of kinematics to find the distance moved by the object
here we know that
initial speed 
final speed 
time taken by the car to stop
now the distance moved by the car before it stop is given as
now we have
