Answer:
-15 m/s
Explanation:
The computation of the velocity of the 4.0 kg fragment is shown below:
For this question, we use the correlation of the momentum along with horizontal x axis
Given that
Weight of stationary shell = 6 kg
Other two fragments each = 1.0 kg
Angle = 60
Speed = 60 m/s
Based on the above information, the velocity = v is
= -15 m/s
Answer:
Hydraulic press is called an instrument for multiplication of force. Why? Because it uses Pascal's idea and principle: F=p*S. If we apply small force to small piston you will generate a pressure. According to Pascal's law pressure is the same everywhere in closed system so the same pressure will act on large piston on the other side too.
Explanation:
Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
C. sulfur dioxide, carbon dioxide, and
nitrogen oxides
These three chemical compounds play a
role in the chemistry of acid rain or acid precipitation. These compounds are
then in the process as they evaporate are converted into acids, mainly, nitric
acid and sulfuric acid. These toxic gases that composes acid precipitation is
actually caused by industries, factories or plants that utilizes such chemicals
and then uses a humongous amount which then is released in during the process
of certain products or manufactured objects.
