We are 8 light minutes from the sun. That means two things, we see the sun as it was 8 minutes ago, and we WOULD continue to see the sun for 8 minutes after it disappeared.
Answer:
Explanation:
Given
mass of sailboat 16300 kg
Eastward Force=17300 N
Northwest Force=59000
Resultant Force F is given by vector addition of two
|F| gives resultant magnitude
|F|=48340.48 N
therefore acceleration is given by
Answer:
The new force will become 1/4 times of the initial force.
Explanation:
The Coulomb force between two charges is directly proportional to the product of charges and inversely proportional to the square of the distance between them.
It can be given by :
....(1)
r is distance
If we decrease the r by a factor of 2, r'=2r.
New force will become,
So, the new force will become 1/4 times of the initial force.
Explanation:
It is given that,
Frequency of vibration, f = 215 Hz
Amplitude, A = 0.832 mm
(a) Let T is the period of this motion. It is given by the following relation as :
(b) Speed of sound in air, v = 343 m/s
It can be given by :
Hence, this is the required solution.
There are two main points that should be emphasized about the different types of electromagnetic radiation. The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy
hope this helps you!✌
