Do you think there is magnus force acting on the earth

suggest why it is better to use light gates and a computer than to use a stopwatch and a ruler to measure the speed of a toy car

grandymaker [24]

Human response times are eliminated from time measurement using light gates. if the stopwatch is damaged, the data logger terminates it.

<h3>What is speed?</h3>

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while u for the final speed. its si unit is m/sec.

To measure the speed of a toy automobile, it is preferable to utilize light gates and a computer as opposed to a stopwatch and a ruler.

Because Light gates eliminate the effects of human reaction delays for measuring time. is damaged,

The stopwatch is stopped by the data logger. With no reaction time, the uncertainty is substantially reduced.

The average speed may be determined by measuring the distance between the two light gates.

Hence, it is better to use light gates and a computer than to use a stopwatch and a ruler to measure the speed of a toy car.

A string trimmer is a tool for cutting grass and weeds; it utilizes a length of nylon "string" that rotates about an axis perpen

olga2289 [7]

Answer:

0.28899 m

Explanation:

v = Velocity = 69 m/s

$\omega$ = Angular velocity = $39\times 2\pi\ rad/s$

r = Radius of the motion

In rotational motion velocity is given by

$v=r\omega$

$\\\Rightarrow r=\dfrac{v}{\omega}$

$\\\Rightarrow r=\dfrac{69}{38\times 2\pi}$

$\\\Rightarrow r=0.28899\ m$

The length of the rotation string is 0.28899 m

dlinn [17]

The portions of the electromagnetic spectrum are used in the television set. It is used in the picture tube in the old television set.

<h3>What is the electromagnetic spectrum ?</h3>

The electromagnetic radiation distribution in accordance with the frequency or wavelength is known as the electromagnetic spectrum.

The portions of the electromagnetic spectrum are used in the television set. It is used in the picture tube in the old television set.

Hence, option b is correct.

Hi guys!!! i have no more points, can someone nice guess all of these for me? :)

NeTakaya

1. The ocean water collects back in the ocean.

2. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

3. an excessive amount of water flowing from downslope along earths surface

4. A.Evaporation occurs when water is warmed by the sun.

5. The water returns into the ocean by the water cycle . It evaporates , then it condensates , then it participates ( Rains ) and then goes back into the ocean.

Hope this answer correct ✌️
