mars1129 [50]

Answer:

The correct answers are -

1. b. pump the brake pedal rapidly

2. d. all of the above

3. c. your power brakes and power steering won't work very well

4. a. gasoline

5. b. power-assist failure

Explanation:

Brakes help in stopping the vehicle by causing resistance to wheels. IF brake failure it is advised to pump the breaks rapidly in order to cause resistance. Engine failure can be caused by various reasons such as a broken timing gear, no fuel, or getting extremely heated.

In the case of stalling of engine most common effects as power steering not working properly or power brakes not working well. The flooded engine means the engine has too much gasoline that it wont starts.

An object has 600J of kinetic energy from its motion and a speed of 10m/s. What is it's mass?
Gemiola [76]

Answer:

The mass is 12 kg

Explanation:

KE = \frac{1}{2} mv²

Substitute:

600 = \frac{1}{2} m(10)²

600 = \frac{1}{2} m 100

600 = 50m

m = \frac{600}{50}

m = 12

A series RLC circuit consists of a 52.0 Ω resistor, a 4.80 mH inductor, and a 330 nF capacitor. It is connected to an oscillator
Tju [1.3M]

Answer:

(G) 75.11 ohm

(H) 0.08 A

(I) 46.2 degree

Explanation:

R = 52 ohm

L = 4.8 m H = 4.8 x 106-3 H

C = 330 nF = 330 x 10^-9 F

Vo = 6 V

(G)

f = 5000 Hz

Let the impedance is Z.

X_{L}= 2 \pi fL = 2 \times 3.14\times 5000\times 4.8\times 10^{-3}=150.72 ohm

X_{c}= \frac{1}{2 \pi fC}=\frac{1}{2\times 3.14\times 5000\times 330\times 10^{-9}}=96.51 ohm

Z=\sqrt{R^{2}+\left ( X_{L}-X_{c} \right )^{2}}

Z=\sqrt{52^{2}+\left (150.72-96.51)^{2}}=75.11 ohm

(H) Let Io be the peak current

I_{0}=\frac{V_{0}}{Z}=\frac{6}{75.11}=0.0798 A = 0.08 A

(I) Let Ф be the phase angle

tan\phi = \frac{X_{L}-X_{C}}{R}

tan\phi =\frac{150.72-96.51}}{52}=1.0425

Ф = 46.2 degree

Igneous rock can be changed into which type of rock through the application of heat and pressure?
marin [14]

Answer:

metamorphic rock

Explanation:

Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.

Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.

  • At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks.
  • These changed rocks have different mineral facies that are different from those of the prolith.

Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.
