This is so you can reach the gas petal, break petal, steering wheel, (and other things) easier so you won't have to lean forward and it makes it easier for when you're driving. Especially if you need to quickly press your breaks, you'll be able to do this a lot faster if you're closer to them than if you had to reach in order to do so.

Line segment gj is a diameter of circle l. angle k measures (4x 6)°. circle l is inscribed with triangle g j k. line segment g j is a diameter. line segments g k and k j are secants. angle k has a measure of (4 x 6) degrees. what is the value of x? 21 24 32 44

Answers

The value of x in the given right triangle in a semicircle is determined as 21.

What is the measure of a triangle in a semicircle?

The triangle in a semicircle is always a right angle triangle.

From the figure shown, we can say that the triangle  G J K is right triangle and m<K = 90degrees.

Given that m<K = 4x + 6, we will can use the following equation to find the value of x as shown:

4x + 6 = 90

4x = 90 - 6

4x = 84

x = 21

Thus, the value of x in the given right triangle in a semicircle is determined as 21.

A common practice for a person with a high fever is to take a bath in cool water. Assuming an 80 kg person is really ill and needs to cool down from 40°C to 37°C. What is the minimum amount of water needed for bathing assuming the water begins at room temperature, 25°C?

Answers

The minimum amount of water needed for bathing assuming the water begins at room temperature is 16.58kg.

What is thermal equilibrium?

When two bodies at different temperature come into contact, they share the heat through conduction. After some time, temperature of both becomes equal. This condition is said to be a body in thermal equilibrium with other.


Heat gained
by the water = heat lost by the ill person

m x Cw x ΔT = M x Cp x Δt

where, mass of person M = 80kg, Cp =specific heat of body =3470, specific heat of water Cw= 4186, then mass of water m will be

m x 4186 x (37-25) =- 80 x 3470 x (37-40)

m = 16.58kg

Thus, the mass of water needed is 16.58kg.

A force applied to a spring compresses the spring 11 cm, storing a certain amount of elastic potential energy. Then a larger force is applied to compress the spring a total of 66 cm. How does the elastic potential energy stored in the spring after it is compressed 66 cm compare to the elastic potential energy stored in the spring after it was compressed 11 cm

Answers

Let k be the spring constant.

• When the spring is compressed by 11 cm = 0.11 m, it stores

1/2 k (0.11 m)²

of potential energy.

• When it's compressed by 66 cm = 0.66 m, it stores

1/2 k (0.66 m)²

of potential energy.

Then the ratio of these potential energies is

(1/2 k (0.66 m)²) / (1/2 k (0.11 m)²) = 36

which is to say, the spring stores 36 times more energy when it's compressed by 66 cm compared to 11 cm.

A generator is operating with 5% droop primary control. The generator is rated for 100 kW. Its secondary power command at this point in time (in other words, the power commanded to produce at 60 Hz) is 67 kW. The grid frequency is currently 59.9 Hz. What is the generator power

Answers

The generator power will be 59 kW. Power drop is the main factor for finding the generated power.

What is the power rating?

The maximum power input allowed to pass through a piece of equipment is known as the equipment's power rating.

Power drop = 5%

The relation of the frequency change with the power drop is;

[tex]\rm \frac{df}{dp} =5\%\\\\ \frac{f_{rated-f_1}}{P_{rated}-P_1}=0.05\\\\ \frac{f_{rated-60}}{100-61}=0.05\\\\ f_{rated}=61.95[/tex]

For the grid frequency, 59.9 Hz


[tex]\rm \frac{f_{rated-f_2}}{P_{rated}-P_2}=0.05[/tex]

[tex]\rm \frac{61.95-f_2}}{100-P_2} =0.05\\\\ 100-P_2 =20(61.95-59.9)\\\\P_2=100-41 \\\\ P_2=59 \ kW[/tex]

Hence, the generator power will be 59 kW.
