Answer: has wavelengths that are longer than visible light
Explanation: Electromagnetic spectra comprises of different electromagnetic waves which are arranged in order of increasing wavelengths or decreasing energies.
In order from highest to lowest energy, the waves are arranged as: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
E= energy
h= planck's constant
c= velocity of light
= wavelength
As wavelength and energy are inversely related, the wave having higher wavelengths will be lowest in energy. Thus as infrared radiation have lower energy as compared to visible radiation. Thus infrared radiation have higher wavelength as compared to visible radiation.
Answer:
1.15 rad/s²
Explanation:
given,
angular speed of turntable = 45 rpm
=
=
time, t = 4.10 s
initial angular speed = 0 rad/s
angular acceleration.
Hence, the angular acceleration of the turntable is 1.15 rad/s²
Answer:
Normal force
Explanation:
- The force is centipetral force
Calculating :-
- Mass=m=20kg
- Radius=r=4m
- Velocity=10m/s=v
We know
Answer: F= 10⁻¹¹ N
Explanation:
We are given that a molecular motor moves in steps of 100 Å.
The energy change for ATP hydrolysis is –60 kJ•mol⁻¹
Now we have to find the maximum resistive force against which motor can move cargo.
So the force will be equal to the energy value divided by the distance in meters.
F= = −6000000000
Ignoring the minus sign.
And for one molecule of ATP per step, the value is divided by Avogadro's number.
F=
F= 10⁻¹¹ N
