Answer:
C, H, N, O, P, S
Explanation:
carbon, hydrogen, oxygen, phosphorus, and sulfur are the 6 most common in biomolecules
Answer:
(a) F = 239.575 N (b) t = 0.00649s or 6.49 ms
Explanation:
(a) By law of energy conservation, the bullet kinetic energy will be transferred to work done on stopping it from moving.
Formula for Kinetic Energy where m is bullet mass, v is the velocity
Formula for work where F is the average force and S is the distance travelled.
Substitute m = 4.2 g = 0.0042 kg, v = 370 m/s and S = 1.2 (m)
(b) If the force is constant, since the mass is constant and F = ma according to Newton's 2nd law, the acceleration on bullet is also constant
We also have
At the time the bullet is coming to rest,
Therefore,
Answer:
A.
collect samples.
Explanation:
The main goal of science is to gain knowledge about the natural world, but this goal is nearly impossible to achieve without technology.
Technologies are products or processes that are created to solve a problem and/or take care of a human need. Technology is often used in science to collect samples, make measurements, collect and store data, analyze data through computations and graphing, and access remote locations, such as outer space.
