Answer:
Extreme temperatures can increase demand for heating and cooling, and the resulting increases in electricity demand can push up fuel and electricity prices.
Explanation:
The reading of the voltmeter can be determined by finding the potential difference across the 2Ω resistance by using the value of current in the circuit. V=IR, here V is the potential difference across a resistance R through which a current I is flowing.
Answer:
4 blocks west is final displacement. So 4 blocks per hour
Answer:
25.59 m/s²
Explanation:
Using the formula for the force of static friction:
--- (1)
where;
static friction force
coefficient of static friction
N = normal force
Also, recall that:
F = mass × acceleration
Similarly, N = mg
here, due to min. acceleration of the car;
![N = ma_{min}](https://tex.z-dn.net/?f=N%20%3D%20ma_%7Bmin%7D)
From equation (1)
![f_s = \mu_s ma_{min}](https://tex.z-dn.net/?f=f_s%20%3D%20%5Cmu_s%20ma_%7Bmin%7D)
However, there is a need to balance the frictional force by using the force due to the car's acceleration between the quarter and the wall of the rocket.
Thus,
![F = f_s](https://tex.z-dn.net/?f=F%20%3D%20f_s)
![mg = \mu_s ma_{min}](https://tex.z-dn.net/?f=mg%20%3D%20%5Cmu_s%20ma_%7Bmin%7D)
![a_{min} = \dfrac{mg }{ \mu_s m}](https://tex.z-dn.net/?f=a_%7Bmin%7D%20%3D%20%5Cdfrac%7Bmg%20%7D%7B%20%5Cmu_s%20m%7D)
![a_{min} = \dfrac{g }{ \mu_s }](https://tex.z-dn.net/?f=a_%7Bmin%7D%20%3D%20%5Cdfrac%7Bg%20%7D%7B%20%5Cmu_s%20%7D)
where;
and g = 9.8 m/s²
![a_{min} = \dfrac{9.8 \ m/s^2 }{0.383 }](https://tex.z-dn.net/?f=a_%7Bmin%7D%20%3D%20%5Cdfrac%7B9.8%20%5C%20m%2Fs%5E2%20%7D%7B0.383%20%7D)
![\mathbf{a_{min}= 25.59 \ m/s^2}](https://tex.z-dn.net/?f=%5Cmathbf%7Ba_%7Bmin%7D%3D%2025.59%20%5C%20m%2Fs%5E2%7D)
