Answer:
Explanation:
A )
As the two bicycles come closer , the time period of oscillation of bee to oscillate between the two is gradually reduced . It is akin to a pendulum with gradually decreasing amplitude . It will be infinite number of trips the bee will travel before it gets squished .
B )
The bee will survive until the two bicyclists meet each other .
time of their meeting = distance between them / their relative velocity
= 20 / ( 10 + 10 )
= 1 hour .
C )
Total distance travelled by bee during 1 hour
= time x speed of bee
= 1 x 30 km/h
= 30 km .
I think the answer is c AC power source

Answer:
D. Nothing will happen; the seesaw will still be balanced.
Explanation:
D. Nothing will happen; the seesaw will still be balanced. Since both toruqes or momentums respect to the center have changed in the same amount (one-half their original distance) the seesaw will remain balanced, if the children change distance in a different amount then it will be out of balance
Answer:
Explanation:
Given that,
The masses of two objects, m₁ = m₂ = 1 kg
The distance between masses, d = 1 m
We need to find the gravitational force between two masses. The force is given by the relation as follows :
So, the force between two masses of 1 kg is 
.
Answer:
4.53482 m/s
4.506 m/s
Explanation:
= Mass of player = 75 kg
= Initial velocity of player = 4.6 m/s
= Mass of ball = 0.47 kg
= Initial velocity of ball = 15 m/s
The linear momentum of the system is conserved
The player's speed is 4.53482 m/s
In the second case the equation of momentum is
The player's speed is 4.506 m/s
