a shot putter accelerates a 7.3kg shot from rest to 14m/s in 1.5r seconds. what average power was developed?

Sedaia [141]

Explanation:

$power = \frac{energy \: expended}{time}$

m = 7.3kg

u = 0

v = 14m/s

t = 1.5sec

P = (0.5×7.3×14²) ÷ 1.5

P = 476.93

P = 477 watt

An open bed truck is moving at 20 m/s and comes to a stop. A 100 kg crate sitting in the back of the truck remains at rest in th

zzz [600]

The work done was done by friction to keep the crate from moving as the truck came to a stop is 20,000 J.

<h3>Work done by friction to prevent the crate from moving</h3>

The work done is determined by applying the principle of conservation of energy.

W = K.E

W = ¹/₂mv²

where;

m is mass of crate
v is speed of the crate with respect to the truck = 20 m/s

W = ¹/₂(100)(20²)

W = 20,000 J

Thus, the work done was done by friction to keep the crate from moving as the truck came to a stop is 20,000 J.

For resistors in series, the equivalent resistance is _____ of their values.

Stels [109]

Answer: The correct answer is "the same as the sum".

Explanation:

The expression for the equivalent resistance in the series combination of the circuit is as follows;

$R'=R_{1} +R_{2} +R_{3}$

Here, R' is the equivalent resistance, $R_{1},R_{2},R_{3}$ are the resistances.

The expression for the equivalent resistance in the parallel combination of the circuit is as follows;

$\frac{1}{R'} =\frac{1}{R_{1}} +\frac{1}{R_{2}}+\frac{1}{R_{3}}$

Here, R' is the equivalent resistance, $R_{1},R_{2},R_{3}$ are the resistances.

In the series combination of the circuit, the equivalent resistance is more than the equivalent resistance in the parallel combination of the circuit.

In the series combination of the circuit, the same amount of current flows across the resistance but the voltage is different across the resistances.

Therefore, for resistor in series, the equivalent resistance is the same as the sum.
