In a stronger gravitational field a given mass will have a larger weight.
Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
- Velocity is a vector quantity, which consists of a magnitude (the speed) and a direction. In the case of the circular motion, as in this problem, the speed is constant (45 m/h), but the direction is constantly changing, so the velocity is changing as well.
- Acceleration is also a vector quantity, whose magnitude is equal to the rate of change of the velocity, and the direction is given by the change in direction of the velocity. Therefore, since the velocity is changing, the acceleration in this problem is changing as well.
The right answer is true because particles are allowed to freely move in gases but in liquids the particles can not leave the other particles, they may move freely but with other particles but gas particles can be found individually roaming around
When rounding you look at the number right after the one you want to round. The tenth place is the one right after the decimal. If the number after it is more than five it goes up by one, it it's less than five it stays the same. So since the number after the 8 is a 3 it stays the same.
The answer is 7.8
