It stops accelerating when the air resistance is equal to its weight.
That's (m•g)

= (2 kg) • (9.8 m/s^2)

= 19.6 newtons

Which order shows increasing energy of photons?
Alchen [17]

The correct answer is C. microwaves, infrared, visible, gamma rays

Electromagnetic waves arranged in order of  frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.

Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.

According to the Einsteins equation, E=hf, Energy is  directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.

Alice and Bob sit on a see saw, that consists of a uniform beam of mass 20kg and a fulcrum rock, that acts as a pivot point. The
tankabanditka [31]

Answer:

Explanation:

Given

Mass of alice M_a=50 kg

Mass of bob M_b=70 kg

Mass of beam M=20 kg

Suppose fulcrum is at distance of d from bob thus From diagram

Equating torque i.e. torque of Bob,Alice and beam must cancel out each other to be balanced

500\times (8-d)+20\times (4-d)=70\times d

400-50d+80-2d=70d

480=140d

d=\frac{480}{140}

d=3.43 m
