Which of the following instrument is used for measuring gauge pressure? a.Thermometer b.Barometer c.Manometer d.Hydrometer

Answer:

1.5 if three resistance are connect in parallel

Answer:

Pl look at basic equation

P = VI

I = V/R

Therefore Power = V * (V/R) = V^2/R

V^2 = P/R

Given Power = 0.5 W

R = 98 Ohms

Therefore V^2 = 0.50/98 = 0.0051

Taking Sq root V = sq root(0.0051)

V = 0.0714 Volts

= 71.4 mV

P=I^2*R

2=I^2*120

2/120=I^2

SQRT(2/120)=I

I=0.12909944487 A or 129.1mA

Knowing I and R, you calculate the voltage across it in this case:-

V=I.R

V=0.12909944487*120

V=15.4919333848 V or 15.5V

Those are your exact values for current and voltage with that resistor… to run the rounded numbers:-

P=V*I

P=15.5*0.1291

P=2.00105W

where

initial KE=0

final PE=0

so

initial PE= final KE

initial PE=m*g*h

where

m=mass= 100g which must be in kg (1000g=1kg) so (100g*1kg)/1000g=0.1kg

g= acceleration due to gravity=9.80m/s^2

h= height= unknown

formula for finding the height is

h=L-L*cos theta= L(1-cos theta)

where

L=length of the string=1m

cos theta=cos of 60 degrees=0.5

h=1(1–0.5)

h=0.5m

using the formula

initial PE= final KE

initial PE=m*g*h

initial PE=0.1*9.80*0.5=0.49J

kinetic energy=0.49J

confirming that my answer is correct by using the formula for kinetic energy

Correct option is C)

Tremors on the earth can be caused when a volcano erupts, or a meteor hits the earth, or an underground nuclear explosion or an earthquake.

The tremors produce waves on the surface of the earth. These are called seismic waves.
