Answer:
19÷5 time equals speed upon distance so 950÷250 will give 19/5 hours
Answer:
-140
Explanation:
A gas loses 80joules of heat.
The gas also does 60 joules of work
Therefore the change in internal energy can be calculated as follows
= -80 + (-60)
= -80-60
= -140
Hence the change in internal energy is -140
Answer:
Acceleration is 9.8 m/s^2
Explanation:
If the boulder falls from the cliff then the gravitational force will apply on it and due to gravitational force, the acceleration will be generated. Moreover, the acceleration generated in this case will be called the acceleration due to gravity. Therefore, the acceleration will remain constant irrespective of time and height because the gravitational force is constant. Thus, acceleration is 9.8 meters per second square.
The answer is 16.6. What you do is divide 3 divide by 3 which equals 1 and so you do 50 divide by 3 which equals 16.6
