A block of mass m1=3.7kg on a smooth inclined plane of angle 30 is connected by a cord over a small frictionless pulley to a second block of mass m2=2.3kg hanging vertically. Calculate the acceleration of each block
Answers
consider the forces on mass m₁ on the incline plane :
parallel to incline , force equation is given as
T - m₁ g Sin30 = m₁ a
T = m₁ g Sin30 + m₁ a eq-1
consider the force on mass m₂ on the incline plane :
m₂ g - T = m₂ a
T = m₂ g - m₂ a eq-2
Using eq-1 and eq-2
m₂ g - m₂ a = m₁ g Sin30 + m₁ a
inserting the values
(2.3 x 9.8) - 2.3 a = (3.7 x 9.8) Sin30 + 3.7 a
a = 0.74 m/s²

What is Electrical energy?
When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible. When two charges are in opposition to one another, they repel one another.
The term "neutral" refers to an object that has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand taking into account quant phenomena.
As per the given information in the question,
Voltage, V = 6 V
Current, I = 0.3 A
Use the equation of ohm's law,
V = RI
6 V = R(0.3)
R = 6/0.3
R = 20 Ω.

It starts from rest, and its speed increases by 9.8 m/s every second.
One tenth the speed of light is (1/10) (3 x 10⁸ m/s) = 3 x 10⁷ m/s .
To reach that speed takes (3 x 10⁷ m/s) / (9.8 m/s²) = 3,061,224 seconds .
That's about 35 days and 10 hours.
(b).
Distance traveled = (average speed) x (time of travel)
Average speed = (1/2) of (1/10 the speed of light) = 1.5 x 10⁷ m/s .
Time of travel is the answer to part (a) above.
Distance traveled = (1.5 x 10⁷ m/s) x (3,061,224 sec) = 4.59 x 10¹³ meters
That's 45.9 billion kilometers.
That's 28.5 billion miles.
That's about 6.2 times the farthest distance that Pluto ever gets from the Sun.

Answer:
True
Explanation:
An optical fiber is like a glass tube with very small radius. The light travels through these fiber following Total Internal Reflection principle. The movement of the light is not affected by the external factor or the shape of the fiber as long as it is intact. Even if it is twisted or curved, the light will travel as long as the fiber is not damaged physically.
the correct answer is true
