A car travels at a constant speed around a circular trackwhose

Mashutka [201]

Answer:

a = 0.77 m/s^2

Explanation:

The centripetal acceleration is given as

$a = \frac{v^2}{R}$

The velocity of the car can be calculated using the circumference of the track and the period of the car.

$2\pi R = v T\\2\pi 2.6 = v 360\\v = 0.045 ~km/s = 45~m/s$

So, the acceleration is

$a = \frac{45^2}{2.6\times 10^3} = 0.77~m/s^2$

Calculate the amount of charge necessary to exert a force of 35 N in an electric field of 300 N/C.

densk [106]

Answer:

The amount of charge is "0.117 C" i.e., option A.

Explanation:

The given values are:

Force,

$\vec{F}$ = 35 N

Electric field,

$\vec{E}$ = 300 N/C

Charge,

q = ?

As we know,

⇒ $\vec{F}=q\vec{E}$

On substituting the given values in the above formula, we get

⇒ $35=q\times 300$

⇒ $q=\frac{35}{300}$

⇒ $q=0.117 \ C$

Explanation:

Two technicians are discussing the testing of a catalytic converter. Technician A says that a vacuum gauge can be used and observed to see if the vacuum drops with the engine at 2500 RPM for 30 seconds. Technician B says that a pressure gauge can be used to check for backpressure. The following technician is correct:
