Answer:
Explanation:
Given
mass of spider
Largest amplitude can be obtained by Tapping after every 3 second
i.e. Time period of oscillation is
considering spider to execute Simple harmonic motion
time of oscillation is given by
substituting values
To solve the problem it is necessary to apply the conservation equations of the moment.
The conservation equation of the moment is defined as,
Where,
Mass of Bird
Mass of Insect
Velocity Bird before swallowing
Velocity of insect
final velocity (both)
Replacing with our values we have,
Therefore the bird's speed immediately after swallowing is 7.83m/s
Answer:
d) 14Ω
Explanation:
series resistors add so therefore 2+4+8=14
186 netwons on Mars and 490 netwons on earth
Answer:
Explanation:
Heat absorb, Q = 10 kWh
Work, W = 9 kWh
As by 1 st law of inventor
Q = W
But here, Q ≠ W , so the machine is perpetual motion machine of 1 st kind.
