Answer:
The fulcrum of the metre stick is at the 40 cm mark
100 g * 10 cm = 1000 g-cm clockwise torque
x * 30 cm = 1000 gm-cm = counterclockwise torque for balance
X = 1000 / (40 -10) = 1000 / 30 = 33.3 gm at 10 cm to balance
Answer:
yeah
Explanation:
electric fields help the charged particles interact
and isn't magnetic field the same as electric field.
To solve this problem it is necessary to apply the concepts concerning the conservation of both potential and thermodynamic energy of the body. That is to say that as the body has a loss of potential energy it is gained in the form of thermal energy on water. If the potential energy is defined as

Where,
m= mass
g = Gravitational acceleration
h = Height
And thermal energy is obtained as

Where,
= Change in Temperature
Specific Heat
m = Mass
We can equate this equation and rearrange to find the change at the Temperature, then


Our values are given as,
Specific Heat Water
Using energy conservation


Replacing,


Therefore the temperature increase in a 1kg sample of water is 1.89K
The best answer would be C. Amplitude is the measure of the distance between the crest and the center of the line, or the distance between the trough and the center of the line (like wave height). High waves are a sea danger, especially to small ships and rowboats.
