Answer:
750,000
Explanation:
I just looked it up on Google lol. You apparently multiple by 1000
Hope this helps :p
Answer:
force and leverage distance
Explanation:
the formula for torque if = force x distance
(the distance above is the leverage distance on the crow bar)
therefore if there is an increase in either the torque or the leverage distance, or both, the torque exerted by the crow bar also increases.
for example
- lets assume a force of 5 n is applied on the crow bar with a leverage distance of 2 m.
the torque = 5 x 2 = 10 N.m
- but if the force was increased to 7 N
torque = 7 x 2 = 12 N.m
from the illustration above, we can see that the torque increased with an increase in force. There would also be an increase in torque if the distance were to be increased.
Answer:
The new force between the charges becomes double of the initial force.
Explanation:
The force acting between charge particles is given by :
k is electrostatic constant
r is distance between charges
If one of the charges are doubled, then, q₁ = 2q₁
The new force becomes,
So, the new force between the charges becomes double of the initial force.
Answer: 567 N
Explanation:
If the weight of the person and the bike are supported equally by the two tires, this means that the force acting on each tire, is half of the total weight.
We know that the gauge pressure in one tire, by definition, is equal to the force on the tire, over the contact surface between each tire and the road, so we can write:
P= F/A = (mrider g + mbike g) / A = (Fgrider + 7.5 kg. 9.8 m/s2) / 703 mm2 (1)
As the pressure data is given in lb/in2, it is needed to convert to N/mm2, as follows:
65.5 lb/in2 = 0.455 N/mm2.
Replacing in (1), and solving for Fgrider, we have:
Fgrider = 567 N
