Answer:
Increase
Explanation:
The plane strain fracture toughness of a metal is expected to increase with rising temperature.
Answer:
Angle of refelction is 60°
Explanation:
Let two mirrors XY and ZY meet at Y such that ∠XYZ = 30°
Let an incident ray PO incident on the 1st mirror XY and is parallel to the 2nd mirror YZ.
Let ON be the normal.
Now we know that , angle of incidence is equal to the angle of reflection
∴∠PON = ∠NOQ =60°
Therefore, the angle of reflection of the ray incident on the 1st mirror is 60 degree.
Answer:
A. Indians who were part of the East India Company’s private army.
Explanation:
The sepoys were Indian soldiers who were recruited into the Company's army. Just before the rebellion, there were over 300,000 sepoys in the army, compared to about 50,000 British. The forces were divided into three presidency armies: Bombay, Madras, and Bengal.
Coulomb's Law for the electric field due to a point charge is
where
E = electric field, V
= Coulom's constant, 8.98755 x 10²
q = point charge, C
r = distance from the pont charge, m
At distance, r, let the electric potential be
At twice the distance from q, the electric potential is
Answer:
At twice the distance from the charge, the electric decreases by a factor of 4.
Answer:
1)Fuel Sourcing
2)Power Generation
Explanation:
1)Fuel Sourcing
: Fossil fuels must be located, excavated and transported before they can be used. These processes are invasive and detrimental to the land through side effects such as erosion as well as ecological and geologic instability. Then the deposit or well is depleted. Energy from the sun is infinite and free. It can be harnessed and turned into power anywhere a solar panel can be mounted.
2)Power Generation:
Fossil fuels must be burned to produce electricity. Burning them creates unwanted byproducts that can create air and water pollution and release huge amounts of greenhouse gasses into the atmosphere.
