That's 'centripetal acceleration'. It points toward the center of the circle in which the object is traveling, even if it's only a temporary piece of a circle.
Answer:
255.61 m
Explanation:
Use in downwards direction from the moment of flight till the car hits the bottom.
As the car fly off the cliff the velocity of the car in vertical direction will be zero.
Answer:
Explanation
There are two factors that can cause the fusion rate in the sun's core to increase.
1) Rise in the temperature of core:
If the temperature of the sun's core increases then it will increases the nuclear fusion reaction. The nuclear fusion reactions has such a strong dependency on temperature that even a smallest rise in temperature will results in the higher rate of reaction. That is why these reactions happen in the hottest core of the stars.
2) Reduction in the radius of the core:
Density plays a huge role in the nuclear fusion reactions. If the radius of the sun's core decrease then there will be an increase in the density of the core. Thus the gravitational pressure will also increases. In order to resist this increase in pressure the fusion reactions will speed up and their rate becomes higher.
Answer:
The correct answers to the question are
1. Environmental variable c,
2. Input variable a,
3. Output variable b,
4. Input variable a,
5. Input variable a,
6. Input variable a
Explanation:
1. Outside temperature.
This is is an environmental variable regarding where the observation is taking place
2. Duration that the soup was heated before being put in the bowl.
This can be controlled so it is an input variable
3. Temperature of the soup in a student's bowl.
This depends on the initial temperature the soup was heated to so it is an output variable
4. Temperature level to which the soup is warmed up.
Input variable as it can be controlled o varied
5. Insulation of the bowl used for storing the soup.
This is an input variable as the type of bowl can be selected
6. Duration that the soup bowl is open when the server inserts the ladle to serve a student.
server or the operator of the cafeteria
The correct answer should be :
D) the area where the magnetic force is exerted.
Hope this helps,
