A 3 N force pushing to the right on a box causes it to accelerate 6 m/s² to the right. What is the mass of the box? A. 0.5 kg
B. 2 kg
C. 3 kg
D. 18 kg
18 kg would be the answer to that
If you moved to a planet that has the same mass as the earth but twice the diameter, how would your weight be affected?
Explain why hot air goes up
Hot air is less dense than cool air ; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air .
When the temperature of dry air increases, the density of it decreases.As a result, the warmer, and less dense as well, is lighter that normal temperature air.So if warm air currents are under cold air currents, the cold cuurents will go lower.I hope I was helpful.If you any wuestions please contact me
Abus moves to the cast with a speed 10 ms, and a student in the bus moves with a speed 9 m/s to the cust. What is the velocity of the . relative to the bus A. 19 m/s to the cast B. 19 ms to the west c. 1 m/s to the east D. L us to the west.
Answer : The velocity of the student relative to the bus is 1 m/s to the east.
Relative speed : It is defined as the speed of a moving object when compared to the another moving object.
There are two condition of relative speed.
(1) It two bodies are moving in same direction then the relative speed will be the difference of two bodies.
(2) It two bodies are moving in opposite direction then the relative speed will be the sum of two bodies.
As per question,
The speed of bus, = 10 m/s to east
The speed of student, = 9 m/s to east
In this problem, the two bodies are moving in same direction then the relative speed will be the difference of two bodies.
Therefore, the velocity of the student relative to the bus is 1 m/s to the east.
