Formula
S=Vxt
70=Vx2.5
V=70/2.5
V=28 meter/second
This question can be easily solved with newton's second law of motion.
F=ma
a=F/m
=8/0.8
=10m/s^2
Answer:
The dimensional formula of the amplitude of a wave is given by,
[ M⁰L¹T⁰ ]
Where,
M = Mass
L = Length
T = Time
Derivation
The amplitude of wave = Maximum displacement
Since, the dimensional formula of displacement = [ M⁰L¹T⁰ ]
Therefore, the amplitude of a wave is dimensionally represented as [ M⁰L¹T⁰ ]
Answer:
The sun heats the earth through radiation. Since there is no medium (like the gas in our atmosphere) in space, radiation is the primary way that heat travels in space. When the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
Answer:
Wavelength = 0.48 m (Approx)
Explanation:
Given:
Speed of sound = 340 m/s
Frequency = 706 hz
Find:
Wavelength
Computation:
Wavelength = Speed of sound / Frequency
Wavelength = 340 / 706
Wavelength = 0.48 m (Approx)
