Let's check the relationship


So
- Raindrops will fall faster . .
- Also walking on ground would become more difficult as g increases.
Option C is wrong by now .Let's check D once

- So time period of simple pendulum would decrease.
Answer:
- It can be infer that it has a lower frequency.
<em>In the case of electromagnetic waves.</em>
- A short wavelength means a lower energy,
Explanation:
The wavelength is the distance between two consecutive crests or valleys while the frequency is the number of crests that pass for a specific point in an interval of time.
For example, a person makes laundry once a weak.
In this example, the event is represented by the laundry and the interval of time is once a weak
The velocity of a wave is defined as:
(1)
Where
is the frequency and
is the wavelenth
(2)
Notice from equation 2 that the wavelength is inversely proportional to the frequency (when the wavelength increases the frequency decreases).
In the case of electromagnetic waves, a short wavelength means a lower energy, as it can be seen in equation 4 (inversely proportional).

(4)
<u>Answer:</u> 0.774 g/cm^3
<u>Explanation:</u>
Density is measured in g/cm^3
480g / 620cm^3 = 0.774 g/cm^3
Does this help? Sorry if not.
Answer:

Explanation:
From frequency of oscillation

Initially with the suspended string, the above equation is correct for the relation, hence

where k is force constant and m is the mass
When the spring is cut into half, by physics, the force constant will be doubled as they are inversely proportional

Employing f2/ f1, we have

To solve this problem we need to use the proportional relationships between density, mass and volume, together with Newton's second law.
The force can be described as

Where,
m = Mass
g = Gravitational acceleration
At the same time the Density can be defined as

Where,
m = mass
V = Volume
Replacing the value of the mass at the equation of Force we have,

Since the difference between the two forces gives us the total Force then we have to

Where
Force of the water
= Force of plastic
Therefore with the values for this force we have,





Therefore the tension in the thread is 16.412N
