Answer:

The size of a force
The perpendicular distance from the pivot the line of action of force

Explanation:

Factors that affect the moment of a force are;

The size of a force
The perpendicular distance from the pivot the line of action of force

The magnitude of force applied is directly proportional to the moment of force in that for a perpendicular distance d, increased in force applied will result to a higher moment of force. When the perpendicular distance from the pivot is decreased while the force applied remains constant, the moment of force decreases.

A sprinter speeds up to 3 m/s during the last 2 seconds of the race with an

quester [9]

Answer:

The initial speed of the sprinter was 2.2 m/s

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

The following relation applies:

$v_f=v_o+at$

Where a is the constant acceleration, vo the initial speed, vf the final speed, and t the time.

The sprinter speeds up from an unknown initial speed to vf=3 m/s in t=2 seconds with an acceleration of $a=0.4~m/s^2$ .

To find the initial speed, we solve the equation for vo:

$v_o=v_f-at$

Substituting the values:

$v_o=3-0.4*2$

$v_o=3-0.8$

$v_o=2.2~m/s$

The initial speed of the sprinter was 2.2 m/s

A 10-kilogram bicycle is traveling at a speed of 2m/s. what is the bike's kinetice energy?

madam [21]

The kinetic energy of an object of mass m moving with speed v is given by:
$K= \frac{1}{2}mv^2$
For the bicycle in our problem, $m=10 kg$ and $v=2 m/s$ , so the kinetic energy is
$K= \frac{1}{2}(10 kg)(2 m/s)^2=20 J$

Answer:

4000 km

Explanation:

as we know velocity of electromagnetic wave is c

$c = 3 * 10^8 m/s$

frequency given (f) = 76 Hz

wavelength ?

using

$c =f$ λ

λ = $\frac{c}{f}$

λ = $\frac{3 * 10^8}{76}$ ≈4000 km

so final answer λ = 4000km
