Answer: 53 dal
Explanation: 5.3x10=53, to get dal you have to multiply by 10 to get 5.3x10=53.
Hope this helped! Please mark Brainliest!
No because it’s too much different between the real value and measured value
Answer:
acceleration in the new orbit is 8 time of acceleration of planet in old orbit
Explanation:
given data:
radius of orbit = R
Speed pf planet = v
new radius = 0.5R
new speed = 2v
we know that acce;ration is given as
acceleration in the new orbit is 8 time of acceleration of planet in old orbit
<u>Answer:</u>
The following are the things we can learn about energy in roller coaster.
- All roller coasters work using the principle of gravitational energy.
- All roller coaster utilise the Potential energy.
- Roller coasters convert the potential energy into kinetic energy.
- Friction is reduced in roller coasters as it decreases the speed of roller coaster.
Roller coasters do not have engines whereas Gravity pulls them and potential energy gets converted into kinetic energy providing its motion. Due to the friction and air resistance, the energy gets reduced as the ride proceeds.
