A worker uses a cart to move a load of bricks a distance of 10m across a parking lot. if he pushes the cart with a constant forc

andriy [413]

Answer:

2090 J

Explanation:

the work done to move the cart is equal to the product between the force applied and the distance traveled:

$W=Fd$

In this case, the force applied is F=209 N, while the distance covered is d=10 m, therefore the work done is

$W=Fd=(209 N)(10 m)=2090 J$

In a transformer a 120 volt dc Primary of 500 turns is connected to a secondary of 75 turns. What is the Induced voltage in the

oee [108]

Answer:

The induced voltage in the Secondary is 18 volt.

Explanation:

Given that,

Voltage = 120 volt

Number of turns in primary = 500

Number of turns in secondary = 75

We need to calculate the induced voltage in the Secondary

Using relation number of turns and voltage in primary and secondary

$\dfrac{V_{p}}{V_{s}}=\dfrac{N_{p}}{N_{s}}$

Where, $N_{p}$ = Number of primary coil

$N_{s}$ = Number of secondary coil

$V_{p}$ = Voltage of primary coil

Put the value into the formula

$\dfrac{120}{V_{s}}=\dfrac{500}{75}$

$V_{s}=\dfrac{120\times75}{500}$

$V_{s}=18\ Volt$

Hence, The induced voltage in the Secondary is 18 volt.

If it takes 32,000 joules of heat to warm 750 g of water, what was the temperature change?(the specific heat of water is 4.18 J/

Firdavs [7]

Answer:

10.21°C

Explanation:

From the question,we are given;

Quantity of heat = 32,000 Joules
Mass of water = 750 g
Specific heat capacity of water = 4.18 J/g°C

We are required to calculate the change in temperature;

We need to know that quantity of heat is calculated by multiplying mass by specific heat then by change in temperature.
That is;

Q = m × c × ΔT

Rearranging the formula;

ΔT = (Q ÷ (m × c))

= 32,000 J ÷ (750× 4.18 J/g°C)

= 10.21°C

Therefore, the change in temperature is 10.21°C
