Answer:
0.0443 m/s
Explanation:
= Mass of honeybee = 0.15 g
= Mass of popsicle stick = 4.75 g
= Velocity of honeybee
= Velocity of stick = 0.14 cm/s
In this system the linear momentum is conserved
The velocity of the bee is 4.43 cm/s or 0.0443 m/s
Given : Time taken to reach the maximum height t=3 s a=−g=−10m/s

The initial velocity of the ball can be calculated by,
Using v=u+at
∴ 0=u−10×3 ⟹u=30 m/s
Using S=ut+

Answer:
Seismic waves
Explanation:
seismic waves are not represented by electromagnetic graphs, nor can they be reflected on an electromagnetic spectrum. Visible light, radio waves, and microwaves are all electromagnetic waves, which are represented by graphs and electromagnetic spectrums.
Answer:
He also formulated his law of Universal Gravitation in the Principia, which states that every point mass attracts every single other point mass by a force pointing along the line intersecting both point.
Explanation:
Mass of Derrick at a height 4.3 m having 2730 joule of energy is 65 Kg.
<h3>What is the expression of gravitational potential energy near the earth surface?</h3>
- Mathematically, gravitational potential energy near the earth surface= m×g×h
- m= mass of Derrick, g= acceleration due to gravity, h= height at which Derrick present
- Then, mass (m) of Derrick = potential energy/ (g×h)
<h3>What is the mass of Derrick, if he gains 2730 joule of energy at 4.3m above the ground?</h3>
Mass of Derrick= 2730/(9.8×4.3)
= 65 kg
Thus, we can conclude that the mass of Derrick is 65 Kg.
