Answer:
Explanation:
A number can be written in the form of :
Where
m is the real number
n is any integer
In this case, the average distance from the Sun to the Earth is given,
d = 150000000000 meters
There are 10 zeroes in this number. We need to write this number in scientific notation. It is given by :
So, the average distance from the Sun to the Earth is . Hence, this is the required solution.
The photoelectric effect cannot demostrate that light can behave like a wave. It demostrates that light carries energy in quantas and that the packages of energy arrive in a kinetic manner proving that light behaves as a particle. The experiment that demostrates that light behaves like a particle as we as like a wave is the double-slit experiment mixed with the photoelectic particle.
Answer:
F = 2.6692 x 10⁻⁹ N
Explanation:
Given,
The mass of the rock, m = 10 kg
The mass of the boulder, M = 100 kg
The distance between them, d = 5 m
The gravitational force between the two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them. It is given by the formula
<em> F = GMm/d² newton</em>
Where,
G - Universal gravitational constant
Substituting the given values,
F = 6.673 x 10⁻¹¹ x 100 x 10 / 5²
F = 2.6692 X 10⁻⁹ N
Hence, the force between the two bodies is, F = 2.6692 X 10⁻⁹ N
Due to the conservation of electric charge, the current is uniform throughout an electrical circuit.
The answer is B.
Answer: The work done is 245000 J.
Explanation:
The formula for the force due to the weight of the object is as follows;
Here, m is the mass of the object and g is the acceleration due to gravity.
Put m=500 kg and g=9.8 meter per second.
The formula for the work done is as follows;
Here, F is the force and s is the displacement.
Put F=4900 N and s=50.0 m.
Therefore, the work done is 245000 J.
