Answer:
The Richter Scale is used to define the power of earthquakes, it was created by Charles Ritcher in the 1930s to work as a seismogram, regulated and assessed by a seismometer, which responds to ground motions at a distance of around 62 miles from the event, and records the seismograph, a <em>base 10</em> logarithmic scale.
Thereby the most suitable options are <em>A)</em><em>, </em><em>B)</em><em> </em>&<em> </em><em>D)</em><em>.</em>
Answer:
800W
Explanation:
Given the following data;
Voltage = 230 V
Model = VSO Ha
Power = 800 W
Power is calculated by the multiplication of voltage and current flowing through an electric circuit.
Mathematically, power is given by the formula;
Power = current * voltage
The S.I unit for power is Watts and it is a measure of the energy consumption of an electronic device.
Answer:
- 2.425 x 10^5 J
Explanation:
The gravitational potential energy between earth and the bock is given by
Where, G is the universal gravitational constant = 6.67 x 10^-11 Nm^2/kg^2
M is the mass of earth = 5.8 x 10^24 kg
m is the mass of block = 4 kg
r be the radius of earth = 6380 km = 6380 x 10^3 m
by substituting the values in the above expression, we get
U = - 2.425 x 10^5 J
