Answer:
I = 0.75 A
Explanation:
The question is not to calculate the resistance, but to calculate the current. (The resistance is already given by the value of 2 Ohm).
U = I * R
I = U / R
with U = 1.5 V and R = 2 Ohm
I = 1.5 / 2
I = 0.75 A
Answer:
The Earth is 4.543 billion years old
Answer:
Explanation:
There are three types of waves mainly.
1. Mechanical waves : Which needs a medium for there propagation. For example, sound waves
2. Non mechanical waves : Which do not need a medium or their propagation.
for example, light waves
3. Electromagnetic waves : Which are produced due to the interaction of electric and magnetic field. for example, X rays, light waves
The wave motion are of two types.
1. Transverse wave motion
2. Longitudinal wave motion
Answer:
0m/s²
Explanation:
The acceleration of the given body whose motion has been described will be zero.
This is because the body moves with a constant velocity.
Acceleration is defined as the rate of change of velocity with time.
Since in this problem, the velocity is not changing per time, then the acceleration would be zero.
A body moving steadily implies that such body is not changing its motion by the virtue of its velocity and even direction.
Answer:
Stanley Eddington confirmed the theory by his observations and inferences using the solar eclipse
Explanation:
Albert Einstein proposed a theory that energy and mass are interchangeable; termed the theory of special relativity. This can be observed when an object moves with the speed of light. The theory states that all laws in physics are the same for all non-accelerating observers.
Thus,
E = m
This theory could not be proven over many years, therefore it was not fully accepted.
In 1919, Stanley Eddington confirmed the theory by his observations and inferences using solar eclipse. The theory is now very accurate at any given speed when gravitational force tends to zero. This has lead to other observations to prove Einstein's theory.
