Answer:

1/2 m v2^2 = 1/2 m v1^2 - G M m / R      conservation of energy

v1^2 - v2^2 = 2 G M / R      rearranging terms

2 G M / R = 2 * 6.67 * 5.98 / 6.37 E7 = 1.25E8

v1^2 - v2^2 = 1.25E8

v2^2 = v1^2 - 1.25E8 = (1.5^2 - 1.25) * E8

v2 = 1.00E4 = 10,000 m/s

Lizard: A lizard is running in a straight line according to the following: xx(tt) = tt3⁄3 − tt2 + tt He starts at tt = 0. (a) De
insens350 [35]

Answer:

Explanation:

a ) x ( t ) = t³ / 3 - t² + t

v = dx / dt = 3 t² / 3 - 2 t + 1 = t² -  2 t + 1

b ) lizard is at rest , v( t ) = 0

t² -  2 t + 1  = 0

( t - 1 )² = 0

t = 1

c )

velocity is positive when

t² -  2 t + 1  > 0

( t - 1 ) ² > 0

Here we see that LHS is a square so it is always positive whatever be the value of t

So velocity is always positive or lizard is always moving in positive x direction .

d ) It never moves in negative x direction .

e )

a ( t ) = dv / dt = 2t - 2

t = 1

so it has zero acceleration at t = 0 .

You can enter compound units that are combinations of other units that are multiplied together.Torque can be calculated by multi
Paraphin [41]

Answer:

3.0 x 10¹ Nm

Explanation:

Torque = F x r

Where F is force applied and r is perpendicular distance from pivot point . r

is also called lever arm

Here F = 15 N and r = 2.0 m

Torque

= 15 N X 2.0 m

= 3.0 10¹ Nm.

Which of the following statements is true? Sound waves create areas of high and low pressure. Areas of high pressure are called
blsea [12.9K]

Answer:

All of the above

Explanation:

Sound waves are mechanical waves consisting of the oscillations of the particles in a medium. They are longitudinal waves, which means that the vibrations of the particles occur in a direction parallel to the direction of propagation of the wave.

This type of wave consists of alternating regions where:

- the density of the particles is higher: these regions are called compressions, and they correspond to high pressure regions

- the density of the particles is lower: these regions are called rarefactions, and they correspond to low pressure regions
