Answer:
Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function. The population is growing to the power of 2 each year in this case.
If you meant the car travels 10 meters or miles then the answer would be 5m/s because v=d/t (v=10/2)
Answer:
The centripetal acceleration of the rock is decreases by a factor of 3.
Explanation:
Given that,
Radius of circle
Time period = T
Radius of new circle
We need to calculate the velocity
Using formula of velocity
The time period for new circle
The time period remains same.
Put the value in the equation
The acceleration of the rock is
We need to calculate the acceleration of the new rock
Using formula of acceleration
Put the value into the formula
Hence, The centripetal acceleration of the rock is decreases by a factor of 3.
Answer:
The magnitude of the average induced emf is 90V
Explanation:
Given;
area of the square coil, A = 0.4 m²
number of turns, N = 15 turns
magnitude of the magnetic field, B = 0.75 T
time of change of magnetic field, t = 0.05 s
The magnitude of the average induced emf is given by;
E = -NAB/t
E = -(15 x 0.4 x 0.75) / 0.05
E = -90 V
|E| = 90 V
Therefore, the magnitude of the average induced emf is 90V
Responder:
Fy = 2474,8737
Fx = 2474,8737
Explicación:
Dado que :
Dado:
Fuerza, F = 3500 N
Ángulo formado con la horizontal, θ, = 45 °
Los componentes de una fuerza se pueden descomponer en componentes verticales y horizontales.
El componente vertical Fy; y
El componente horizontal Fx
Fy = Fuerza * sinθ
Fy = 3500 * sin45 °
Fy = 2474,8737
El componente horizontal:
Fx = Fuerza * cosθ
Fy = 3500 * cos45 °
Fy = 2474,8737
