Answer:
The paper is placed on the focus of the lens then we get the sharp image.
Explanation:
Given that,
Object distance = 150000000 km
Diameter = 1400000 km
Diameter of lens = 5.2 cm
Focal length = 10 cm
We need to calculate the image distance
Using formula of lens
Here,
Hence, The paper is placed on the focus of the lens then we get the sharp image.
Answer:
V2 = 21.44cm^3
Explanation:
Given that: the initial volume of the bubble = 1.3 cm^3
Depth = h = 160m
Where P2 is the atmospheric pressure = Patm
P1 is the pressure at depth 'h'
Density of water = ρ = 10^3kg/m^3
Patm = 1.013×10^5 Pa.
Patm = 101300Pa
g = 9.81m/s^2
P1 = P2+ρgh
P1 = Patm +ρgh
P1 = 1.013×10^5+10^3×9.81×160.
P1 = 101300+1569600
P1 = 1670900 Pa
For an ideal gas law
PV =nRT
P1V1/P2V2 = 1
V2 = ( P1/P2)V1
V2 = (P1/Patm)V1
V2 = ( 1670900 /101300 Pa) × 1.3
V2 = 1670900/101300
V2 = 16.494×1.3
V2 = 21.44cm^3
Answer: current is 8.0 A
Explanation: R= U/I I = U/R = 120 V/15 Ω= 8.0 A
Force the glove exerts on the ball
Explanation:
The reaction to this force is the force the glove exerts on the ball.
According to Newton's third ;aw of motion "Action and reaction forces are equal and opposite in direction".
- The action force is the impact of the ball against the players glove.
- The reactive force is the force the glove exerts on the ball.
This reactive force is directed in the opposite direction and it is the reason why the motion of the incoming ball is halted.
