Which of the following is a result of a change in pressure? A. Frost wedging B. Chemical feathering C. Oxidation D. Exfoliation

Physics

The answer is D. Exfoliation. Exfoliation is a type of physical or mechanical weathering which is also referred to as release of pressure. It occurs when layers of rock separate from the stripped rocks as an effect of the pressure released during the wearing down of rock particles by friction due to water, wind or ice.

What are the two requirements of a circuit so that current will flow?
antoniya [11.8K]

Answer:

-The battery-the power source

-Closed conducting loop

Explanation:

-To produce an electric current, the following requirements must be met:

-A battery-This is the energy source than will do work on the charge thus moving from a low energy location to high energy location.

-Closed Conducting Loop-The loop is usually made of copper wires due to their high electric conductivity.

A typical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. If the jetliner travels at a const
zzz [600]

jetliner is moving with speed 146 mi/h

now we will have

v= 146 \frac{1609 m}{3600 s}

v = 65.25 m/s

now if it moves with this speed for 1.5 s

so the displacement for above time

d_1 = 1.5(65.25) = 97.9 m

now the deceleration of jet is given as

a = - 10.4 mi/h/s

a = -(10.4)(\frac{1609 m}{3600 s})\frac{1}{s}

a = - 4.65 m/s^2

now by kinematics

v_f^2 - v_i^2 = 2ad

0 - 65.25^2 = 2(-4.65)(d_2)

d_2 = 457.8 m

so total displacement is given as

d = d_1 + d_2

d = 97.9 + 457.8 = 555.7 m

so displacement will be 555.7 m

9) For a horizontally launched projectile, decreasing the height of the
Volgvan

Answer:

Increasing the launch height increases the downward distance, giving the horizontal component of the velocity greater time to act upon the projectile and hence increasing the range.

Blank is a measure of how fast something moves
quester [9]

Answer: average speed  

  The overall rate of speed at which an object moves: calculated by dividing the total distance an object travels by the total time

instantaneous speed >      The speed of an object at one instant in time.

velocity                    >                Speed in a given direction
