Work = force × distance
21000 = force × 12m
we need to rearrange this equation because force isn't on the right side of the equation and it becomes
force = 2100 ÷ 12m
force = 175N
Answer:
Since opposite charges attract each other, the negatively charged electrons are attracted to the positively charged protons. ... Together, all of the electrons of an atom create a negative chargethat balances the positive charge of the protons in the atomic nucleus.
Explanation:
Answer:
Explanation:
Torque created by force 3.34N
= 3.34 x 1.39 = 4.64 N.m
This torque is acting in clockwise direction .
Torque created by force 8.52 N
8.52 x .48
= 4.09 N.m
The force of 8.52 N is acting downward . It may turn the cylinder in clockwise or anticlockwise direction . So we shall consider both the possibilities.
If it rotates the cylinder in clockwise direction
Total torque = 4.64 + 4.09
= 8.73 Nm
If it rotates the cylinder in anticlockwise direction
Total torque = 4.64 - 4.09
= .55 Nm
Net torque will be in clockwise direction.
Answer:
v = 1/3 m / s = 0.333 m / s
in the direction of the truck
Explanation:
The average speed is defined by the variation of the position between the time spent
v = Δx / Δt
since the position is a vector we must add using vectors, we will assume that the displacement to the right is positive, the total displacement is
Δx = 20 - 15 +20
Δx = 25 m
therefore we calculate
v = 25/75
v = 1/3 m / s = 0.333 m / s
in the direction of the truck
