Answer:
The astronaut's mass is 16 kg.
Explanation:
Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Therefore, if an astronaut has a mass of 16 Kg on Earth, his mass on the moon and on the space station would remain the same, as his original mass of 16 Kg because mass is indestructible.
Answer:
Explanation:
= Mass of ball = 0.12 kg
tex]m_{2}[/tex] = Mass of bottle = 2.4 kg
= Initial velocity of ball
= Initial velocity of bottle
= Final velocity of ball =
= Final velocity of bottle
As linear momentum is conserved
The bottle's speed is
Solution :
Given :
The angle of the first maximum with the center is given by :
= 14.5°
The grating distance can be calculated as :
=
When the principal maxima yields at y = 0.488 m and the length from the wall 1.88 m. Thus the equation of the wavelength is :
, where n = 1
