Weight = (mass) x (gravity)
Weight = (100kg) x (9.8 m/s^2)
Weight = 980 kg-m/s^2
Weight = 980 Newtons.
(about 220.5 pounds)
The weight of a 100 kg mass on Earth's surface is 980 Newtons(N). This is calculated using the formula 'w=mg', where 'w' is weight, 'm' is mass, and 'g' is the acceleration due to gravity on Earth (9.80 m/s²).
On earth, the weight of an object is determined by the gravitational force acting on it. This can be calculated using the formula w = mg, where 'w' is the weight of the object, 'm' is its mass, and 'g' is the acceleration due to gravity on Earth. Given that the mass 'm' is 100 kg and the acceleration due to gravity 'g' on Earth's surface is approximately 9.80 m/s², we can determine the weight of the object by substituting these values into the formula.
Applying these values into our equation, we get: w = (100 kg)(9.80 m/s²) = 980 N. Therefore, a 100 kg mass weighs 980 Newtons (N) on Earth's surface.
It is pertinent to note that an object's weight can vary based on its location as the value of 'g' changes with location. For instance, the value of 'g' on the moon is only about 1.67 m/s², which is far less compared to Earth, resulting in a lighter weight for the same mass.

B) 0.0228938 m3
C) 0.5457875 m3
D) 0.0457875 m3
Answer: C) 0.5457875
Explanation: Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
where,
= initial volume of gas =
= initial temperature of gas =
= final volume of gas = 0?
= final temperature of gas =
Thus the final volume is
Answer: No
Explanation:
Electrons have negative charge. It's charge can be decimal because it's about 1.6*10-19 But number of electrons passing through a metal cannot be a decimal number. If you use Q = ne
Q - total charge
e - Charge of an electrone
n - Number of electrons
You might get decimal value for n but it doesnt mean that it shoud have decimal value . Then you have to get nearest less digit value for answer. We cant divide electrons in to pieces
