Answer:
B. In the same group
Explanation:
Elements in the same group shared chemical properties.
Explanation:
The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.
Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units
If the car is on the moon, its mass is about 817 kg.
If it's on the Earth, its mass is about 135 kg.
Answer:
166.6 N
Explanation:
Given that,
Force, F₁ = 20 N
Area, A₁ = 10 dm² = 1000 cm²
We need to find the new force if the area of the larger piston is 120 cm². According to Pascal's law,
So, the force on the larger piston is equal to 166.7 N.
