Answer:
826.36203 m/s²
Explanation:
= Final angular velocity = 470.2 rad/s
= Final angular velocity = 0
= Angular acceleration
t = Time taken
Equation of rotational motion
Magnitude of the average angular acceleration of the disk is 826.36203 m/s²
ANSWER A turbine is a device that harnesses the kinetic energy of some fluid - such as water, steam, air, or combustion gases - and turns this into the rotational motion of the device itself. These devices are generally used in electrical generation, engines, and propulsion systems and are classified as a type of engine.
Answer:
Explanation:
If F be the force acting on the car to stop it
work done by force = change in kinetic energy
F X 80 = 1/2 m x 20²
F = 2.5 m
If speed is 10m/s
for distance d , the equation is
F x d = 1/2 x m x 10²
2.5 m x d = 1/2 x m x 10²
d = 20 m
If velocity is 40 m /s
F x d = 1/2 x m x 40²
2.5m x d = 1/2 m x 1600
d = 320 m
For v = 5 m/s
F x d = 1/2 m x 5²
2.5 m x d = 1/2 m x 5²
d = 5 m .
Alpha particles are released by proton rich unstable nuclei. It has no electrons to balance the protons making it positively charged particles moving at very high speeds. Gamma articles are electromagnetic waves of short wavelength and high frequency. It has a speed same as the speed of light. Beta particles are released by neutron rich unstable nuclei. It has a speed of less than the gamma particles.
