Answer:
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
Explanation:
Given:
Let the primary voltage be,
Secondary Voltage,
Secondary Resistance,
To Find:
a)
b) I₂ = ?
c) Power = ?
d) R₁ = ?
Solution:
The ratio of primary to secondary turns of the transformer, is the ratio of primary to secondary Voltage and is given by,
Substituting the values we get
For, rms current for the secondary supply,
Substituting the values we get
Now for average power at load,
Substituting the values we get
Now for resistance connected directly across the source line Power will remain same,
Substituting the values we get
Therefore,
a)
b) I₂ = 2.55 Ampere
c) Power = 30.6 Watts
d) R₁ = 470.58 ohms.
Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
Answer:
Can behave both as a particle and wave
Explanation:
Electromagnetic wave has the electric and magnetic wave propagating/oscillating together. Electromagnetic waves such as x Ray, gamma ray, radio waves are important in health care and modern information technology .
Electromagnetic waves have particles such as the electrons and protons. They are responsible for the existence of electromagnetic waves by the charged particles vibrating. Electromagnetic waves behave as waves majority of the time. Electromagnetic energy is released in distinct packs of energy called photons which are particles but acts like waves.
In projectile motion horizontal motion has zero acceleration and when there is no air resistance acting on the object the motion will be uniform. Motion in the vertical direction is accelerated downwards to to the acceleration due to gravity
