-- Momentum is (mass) x (speed).
Object B has 1.5 times as much momentum as Object A has.
-- Kinetic energy is (1/2) x (mass) x (speed) .
Object B has 1.5 times as much kinetic energy as Object A has.
-- If they would both stop long enough to get on the scale,
Object B would weigh 1.5 times as much as Object A does.
Answer:
Impossible to know without more information about the fields.
Explanation:
Changing the magnetic field induces the external magnetic field, but the information regarding magnetic field variation is not provided. We need to required more information for this
Therefore according to the above explanation the correct option is Impossible to know without more information about the fields.
Hence, the b option is correct
Answer:
what are u asking there isnt a question
Any form of succession will change the environment. That's why there is succession in the first place. With each stage of succession there will be greater biodiversity that results in a change in abiotic factors like soil composition, shade, humidity, weather, exposure, etc
Answer:
27 m/s²
Explanation:
Traveling in uniform circular motion will cause a centripetal acceleration, an acceleration towards the center of the circle.
The acceleration of an object in circular motion is defined as a = v²/r.
Let's set the radius to be 5 m, since it is always unchanging. Solving for the velocity using a = 3 m/s² and r = 3 m gives us:
The velocity is 3 m/s when the acceleration is 3 m/s² and the radius of the circular path is 3 m.
Now let's triple the velocity: 3 m/s → 9 m/s.
Let's solve for the acceleration using v = 9 m/s and r = 3 m.
- a = (9)²/3
- a = 81/3
- a = 27
The acceleration is 27 m/s² if you triple your speed.
This makes sense because a is directly proportional to v², meaning that if you triple your speed, you increase the acceleration a by a factor of 3², which is a 9 times increase.
As a sidenote, doubling your speed would increase the acceleration by a factor of 2² - a 4 times increase.
