The average speed of the car is

               (the mile marker he passes at the end of the 1.75 h) minus 115
divided by
               (1.75 hours) .

The unit is 'miles per hour'.

disa [49]
Answer:0.507m

To answer this question, you need to know how to calculate a cube volume. Cube volume is calculated by multiplying the length^3, make its unit become cubic meter.
In this case we know the volume is 130L and asked how long is the length in meter. Then you need to convert the liter into m3. The calculation would be:
V=R^3
130L= R^3
R= 3<span>√(130m3/1000)
R= 5.065797/10 m
R= 0.506579m
Rounded up to 0.507m</span>

A 7.0 kg bowling ball has a moment of inertia of 2.8x10-2 kg m2, and a radius of 0.10 m. If it rolls down the lane at an angular
slega [8]

Hi there!

Angular momentum is equivalent to:

\large\boxed{L = I\omega}

L = angular momentum (kgm²/s)

I = moment of inertia (kgm²)

ω = angular velocity (rad/sec)

Plug in the given values for moment of inertia and angular speed:

L = (0.028)(40) = \boxed{1.12 kgm^2/s}

Godric and Savos are a few meters apart, at one end of the football field. Peter is at the other end of the field. Godric and Sa
Troyanec [42]

Answer:

From Savos point of view, Gadros appear not to be moving

Explanation:

The given parameters are;

The distance between Godric and Savos = A few meters

The location of Godric and Savos = One end of the field

The location pf Peter = The other end pf the field

The speed with which Godric and Savos are moving towards Peter = 4 m/s

Let the positive x-direction be the direction in which Godric and Savos are moving

Therefore;

The speed and direction with which Godric is moving = The speed and direction with which Savos is moving = 4·i m/s

From Savos point of view, the relative speed with which Godric is moving = (The speed and direction in which Godric is moving) - (The speed and direction in which Savos is moving) = 4·i m/s - 4·i m/s = 0 m/s

Therefore, from Savos point of view, the relative speed with which Godric is moving = 0 m/s or Gadros appears stationary or not to moving.
