Answer:

$\boxed {\boxed {\sf 8 \ m/s}}$

Explanation:

Speed is equal to distance over time.

$s=\frac{d}{t}$

The distance is 400 meters and the time is 50 seconds.

$d= 400 \ m \\t= 50 \ s$

Substitute the values into the formula.

$s=\frac { 400 \ m }{ 50 \ s}$

Divide.

$s= 8 \ m/s$

The speed of the car is 8 meters per second.

When 15 newtons of force is applied to the 0.5 kg book, the friction keeps the book from sliding down the wall. What is the mini

valkas [14]

Answer:

15 N and 3.061

Explanation:

From the question,

The minimum force of friction to keep the book from sliding = 15 N.

using

F = mgμ................. Equation 1

Where F = Frictional Force, m = mass of the book, g = acceleration due to gravity, μ = coefficient of friction.

make μ the subject of the equation

μ = F/mg............... Equation 2

Given: F = 15 N, m = 0.5 kg, g = 9.8 m/s²

Substitute into equation 2

μ = 15(0.5×9.8)

μ = 15/4.9

μ = 3.061

Hence the coefficient of friction to keep the book from sliding = 3.061

When hot and cold air meet, the hot air rises to the top. What causes the hot air to rise???

vekshin1

Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the airaround it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.

Define the focus of a concave lens

Sophie [7]

Answer:

Principal focus of concave lens - 

★ The point at which rays parallel to principal axis coming from infinity appear to converge after being refracted from concave lens is called the principal focus of concave lens.

________________________

• Additional information - 

★ Principal focus - A number of rays parallel to the principal axis after reflection from a concave mirror meet at a point on the principal axis or appear to come from a point after reflection from a convex mirror on the principal axis. This is called principal focus.
