Answer:
25g
Explanation:
Given parameters:
Half life of X = 5days
Mass of sample of radioactive elements = 100g
The half-life of a radioactive material is the time it takes for a sample to decay by half. At the half-life, an original sample would have yielded equal daughter to parent ratio.
At time (days) Mass of sample
0 100g
5 50g
10 25g
Every 5 days, the sample will split into half.
Therefore, 25g will remain after 10days.
Answer:park lights and license plate illumination lamps
Explanation:
Answer:
it is a measure of the heat content of fuels or energy sources
Explanation:
Answer:
B because the earth rotational axis tilt away from the sun.
For the following statements
A) The motor speed is less than wheel speed.
B) The output power of the motor is positive during hill climbing.
C) The wheel torque is more than motor torque
These assertions are given respectively as
<h3>What are speed, power, and Torque?</h3>
Speed: defined as the ratio of operation with respect to distance and time
Power: defined as the ability to work
Torque: This is the speed of a rotating object
Generally, the equation for Speed, Power, Torque is mathematically given as
V=m/s
P=w/t
T=rfsin\theta
In conclusion
For a moving car, the wheels speed is in equilibrium with the motor speed Hence false
The output power during a hill climb is positive cause work is been done, Hence true
The wheel torque also is in equilibrium with the motor Torque, Hence false
