I think these forms are called isotopes of each other.
Answer:
d. the translucence of the object
Explanation:
the reason is that an object has a particular color as it is translucent to certain colors; it may absorb some colors and not show them at all, or they will reflect the remaining colors, the ones we are able to see. for eg: imagine you have a red dress. you see it as red, yet it is only reflecting the red color into your eyes, and is absorbing every other color in that light's color spectrum.
Answer:
Explanation:
Initial charge,
After conduction, charge on the body becomes,
We need to find the number of electrons gained by this charged body.
Net charge,
Let n be the number of electrons gained by this charged body. So,
So, electrons gained by this charged body.
Answer:
False
Explanation:
Paleobotany is the study of fossil plants.
Answer:
a)
b)
Explanation:
a)
Using the conservation of energy between the moment when the bullet hit the block and the maximum compression of the spring.
Where:
- M is the bullet-block mass (0.00535 kg + 2.174 kg = 2.17935 kg)
- V is the speed of the system
- k is the spring constant (6.17*10² N/m)
- Δx is the compression of the spring (0.0634 m)
Then, let's find the initial speed of the bullet-block system.
b)
Using the conservation of momentum we can find the velocity of the bullet.
I hope it helps you!
