Answer:
All living organisms have complex organization, they are able to grow and develop, they are able to reproduce and pass on genetic information to their offspring, they are able to acquire and release energy, and they are able to maintain stable internal environments.
Explanation:
The second option
You can see it in the name that see represents carbon and H represents hydrogen on the periodic table. The numbers after it are the amount of items that are in the molecule
To solve this problem we will apply the concepts related to wavelength as the rate of change of the speed of the wave over the frequency. Mathematically this is
Here,
v = Wave velocity
f = Frequency,
Replacing with our values we have that,
\lambda = 0.68m
The distance to move one speaker is half this
Therefore the minimum distance will be 0.34m
Answer:
<em>Helen's force must be of 40 N in the same direction as Jo.</em>
Explanation:
<u>Net Force</u>
When a number of forces are applied to an object, the net force is the sum of all the forces considered as vectors.
When all forces act on a straight line, only two possible directions are considered and they can be arbitrarily assigned positive and negative signs.
Jo pulls with a force of 100 N in a direction considered as positive (for example). Daniel applies a force of 140 N in the opposite direction, obviously negative. The net force of these two forces is 100 N - 140 N = - 40 N.
This means there is a resultant non-zero force in the direction of Daniel's. If we are told the net force is zero because of Helen's force, it must be applied in the same direction as Jo's force to balance.
Helen's force must be of 40 N in the same direction as Jo.
Explanation:
It is given that,
Mass of the bullet, m₁ = 0.093 kg
Initial speed of bullet, u₁ = 100 m/s
Mass of block, m₂ = 2.5 kg
Initial speed of block, u₂ = 0
We need to find the speed of the block after the bullet embeds itself in the block. Let it is given by V. On applying the conservation of linear momentum as :
V = 3.58 m/s
So, the speed of the bullet is 3.58 m/s. Hence, this is the required solution.
