A)
Answer: They will fall at the same time.
Explanation: This is a free fall equation. Free fall equations don't use other factors such as air resistance or wind.
B)
Answer: 15m
Explanation:
Given: Vi = 10m/s
t = 1s
a = 10m/s/s
The equation you need to use is d = Vit + 0.5at^2
d = Vi t + 0.5 a t^2
d = (10 m/s) (1 s) + 0.5 (10 m/s^2) (1 s)^2
d = (10 m) + 0.5 (10 m/s^2) (1 s)^2
d = (10 m) + (5 m/s^2) (1 s)^2
d = (10 m) + (5 m/s^2) (1 s^2)
d = (10 m) + (5 m)
d = 15 m
Answer:
Electron Microscope
Explanation:
In contrast to light microscopes, electron microscopes use a beam of electrons instead of a beam of light. Not only does this allow for higher magnification and, thus, more detail, it also provides higher resolving power. The method used to prepare the specimen for viewing with an electron microscope kills the specimen. Electrons have short wavelengths (shorter than photons) that move best in a vacuum, so living cells cannot be viewed with an electron microscope.
Answer:
Mark me as brainlist
Explanation:
يقع الشاطئ الذي تريد الذهاب إليه على بعد 700 ميل ، لذلك قررت حجز رحلة طيران. ومع ذلك ، عليك التخطيط لركوب سيارتك إلى المطار أولاً. ما هي سرعة سيارتك لكل جزء من رحلتك إلى المطار.
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
- Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.
- This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.
- The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.
As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.
