Answer:

Acceleration will 7.5 times g = 7.5 g

Explanation:

Centripetal acceleration is given by a = v²/r.

The speed in m/s will be; (96.6 Km/h )÷ 3.6

                                        = 26.83 m/s.

Centripetal force = v²/r

                            = 26.83²/9.80

                            = 73.454 m/s²

But; g = 9.8 m/s²

Therefore the acceleration in terms of g will be;

  = 73.454/9.8

   = 7.5 g

Acceleration is 7.5 g

Answer:

C2, C1, C4, C5 and C6 are in parallel. Therefore, we use the formula Cp = C1 + C2 + ....

Cp = C2 + C1 + C4 + C5 + C6 = ( 7 * 10 ^-3) + (18 * 10^-6) + (0.8F) + (200 * 10^-3 F) + (750 * 10^-6) = 1.008F

Now, Cp will become one capacitor and it will be aligned with C3, therefore it will now become a circuit in series.

We use the formula: 1/Cs = 1/C1 + 1/C2 + .... + ....1/Cn

Thus,

1/Cs = 1/C3 + 1/Cp

1/Cs = 1/(14 * 10^-3 F) + 1/(1.008F)

Cs = 1.4 * 10 ^-2 or if we do not round too much it will give exactly 0.0138 F

So the answer should be a)

You suspect that a power supply is faulty, but you use a power supply tester to measure its voltage output and find it to be acc
ValentinkaMS [17]

Answer:

Load

Explanation:

A normal power supply can deliver up to certain amount of power to a load. The output power can be calculated multiplying Voltage (V) x Current (A). It happens that after a certain period of time, the power source's main components begin to wear, thus losing its ability to deliver its nominal power. Normally, when no load its connected to the source, you will get the operating Voltage, but when the load demands power, the ability to deliver power to it may fail to reach nominal levels. When connected, there may be voltage drops (thus, less power output) causing malfunctions turning it into a non-operative power supply.

1. If Randy races his F-150 down Highway 1 for 2560 meters in 60 seconds, what is his average speed?
Nimfa-mama [501]

The average speed is 42.7 m/s

Explanation:

The speed of an object in uniform motion (=moving at constant speed) is given by the equation:

v=\frac{d}{t}

where

v is the speed

d is the distance

t is the time

For the car in this problem, we have:

d = 2560 m (distance)

t = 60 s (time)

Solving the equation, we find the average speed:

v=\frac{2560}{60}=42.7 m/s
