7 0

Answer:

<em> The object has frequency of 2 Hz and time period of 0.5 s.</em>

Explanation:

<em>Frequency</em> is defined as number of oscillation per second ie back and forth swings done in single second.

Here it is given that the object oscillates 20 times in 10 seconds.

So f = \frac{20}{10} = 2Hz

The <em>time period</em> is defined as time taken by the object to complete one full oscillation.

T = \frac{1}{f}

T= \frac{1}{2} =0.5 s

<em>Thus the object has frequency of 2 Hz and time period of 0.5 s.</em>

Hello, some examples are Earth science, chemistry and Navigation science (don't know if there is called in this way).

In Earth Science we can talk about Geomagnetism.

In Chemistry, electrostatics and electrochemistry.

In Navigation science the compass.

Hope it helped.

Sever21 [200]

Answer:

Potential gradient = 1.6 v/m  

E.M.F. = potential gradient × balancing length 1.2 = 1.6 × l

l=1.2\1.6

=3\4

An object has a mass of 12 kg. on planet a, the object weighs 69 n. the force of gravity on planet a is:_____.
balandron [24]

the force of gravity on planet a is g = 5.72 m/s2

There is an object that weighs 12 kg. The object's weight on Planet A is 69 N. The equation F=mg, where F is the weight, m is the mass, and g is the force of gravity, can be used to calculate the force of gravity on Planet A:

g = F/m

g = 69 N/ 12 kg

g = 5.72 m/s2

<h3>What is the gravity force?</h3>

The force of attraction between any two objects in the universe is known as gravity or gravitational force. The mass of the object and the square of the distance between them determine the force of attraction. The weakest known force in nature, it is by far.
