P= 10m = 10 x 180 = 1800 N
work is done by the weightlifter in lifting the barbells :
A= Ph = 1800 x 1.95 = 3510 J
ok done. Thank to me :>
V = wf
ex) 5m • 16 Hz = 80 m/s
5m • 20 Hz = 100 m/s
Answer : True because when multiplying the same wavelength with an increase in frequency, will give you a higher velocity (speed).
A fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.
<h3>What is speed density fuel injection system?</h3>
Speed density fuel injection system is a fuel delivery method.
This system relies on a combination of sensor and an intake air temperature sensor to measure the amount (or mass) of air entering the engine.
Thus, a fuel injection system that does not use a sensor to measure the amount (or mass) of air entering the engine is usually called speed density type of system.

Answer:

Explanation:
According to the free-body diagram of the system, we have:

So, we can solve for T from (1):

Replacing (3) in (2):

The electric force (
) is given by the Coulomb's law. Recall that the charge q is the same in both spheres:

According to pythagoras theorem, the distance of separation (r) of the spheres are given by:

Finally, we replace (5) in (4) and solving for q:
