Answer:
<h3>30m</h3>
Explanation:
Velocity is the change of rate of displacement with respect to time.
velocity = displacement/time
Given
initial velocity = 15 m/s.
time taken =2 secs
Required
Displacement of the object
From the formula;
Displacement = Velocity * time
Displacement = 15 * 2
Displacement = 30m
<em>Hence the displacement of the object is 30m</em>
Answer:
A dimension is a measure of a physical variable.
Unit is a way to assign a number or measurement to that dimension.
In dimensional analysis, a dimensionless quantity is a quantity to which no physical dimension is assigned, also known as a bare, pure, or scalar quantity or a quantity of dimension one, with a corresponding unit of measurement is the SI of the unit one, which is not explicity shown.
The appliances with thermostat are designed in such a way that it will provide heat waste energy by converting electrical energy to thermal energy. ... It converts thermal energy into mechanical energy. The nightlight that is used, converts electrical energy to visible light, which is a form of radiant energy.
Wave speed= Frequency x Wavelength
-> Wavelength= Wave speed divide Frequency
-> 50m/s divide 100Hz= 0.5m
