Answer: 0.4 V
Explanation:
Given
The area of the loop is
The magnetic field is changing at the rate of
Induced EMF is given by
The magnitude of induced emf is 0.4 V
D.) All of the above ...........
Height to be reached above is given as
H = 25 m
let say initial speed is "v"
the final speed that will reach must be ZERO
now we will use kinematics
here we know that
now from above equation we will have
so the speed must be 22.15 m/s
<u>Answer:</u>
Given Data:
V2 ?
V1 = 200 ml,
P1 = 500kpa and P2 = 2500kpa
From <em>Boyels law</em> (Ideal gas law) Where temperature remains constant, <em>Pressure is inversely proportional to volume.</em>
P1 .V1 = P2 . V2 ; T=Constant
V2 = (P1.V1) ÷ P2
= (500×200) ÷(250)
= 400 ml
<em>The final volume of the gas is 400 ml.</em>
<em>Note: Increased pressure decreases the volume or decreased pressure increase the volume as they are inversely proportional.</em><em> Here in our answer pressure decreases from 500 kpa to 250 kpa so volume increases from 200 ml to 400 ml. </em>
Answer:
The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.
Explanation:
Weight of the object on the surface of Earth, W = 245 N
On the surface of Earth, acceleration due to gravity, g = 10 m/s²
Weight of an object is given by :
W = mg
m is mass
So, the mass of the object is 24.5 kg
Acceleration due to gravity on Mars, g' = 3.72 m/s²
Weight of the object on Mars,
W' =mg'
W' = 24.5 kg × 3.72 m/s²
= 91.14 N
So, the weight of the object on Mars is 91.14 N.
