Answer:
The dog catches up with the man 6.1714m later.
Explanation:
The first thing to take into account is the speed formula. It is , where v is speed, d is distance and t is time. From this formula, we can get the distance formula by finding d, it is
Now, the distance equation for the man would be:
The distance equation for the dog would be obtained by the same way with just a little detail. The dog takes off running 1.8s after the man did. So, in the equation we must subtract 1.8 from t.
For a better understanding, at t=1.8 the dog must be in d=0. Let's verify:
Now, for finding how far they have each traveled when the dog catches up with the man we must match the equations of each one.
The result obtained previously means that the dog catches up with the man 3.8571s after the man started running.
That value is used in the man's distance equation.
Finally, the dog catches up with the man 6.1714m later.
Answer:
The ball is dropped at a height of 9.71 m above the top of the window.
Explanation:
<u>Given:</u>
- Height of the window=1.5 m
- Time taken by ball to cover the window height=0.15
Now using equation of motion in one dimension we have
Let u be the velocity of the ball when it reaches the top of the window
then
Now u is the final velocity of the ball with respect to the top of the building
so let t be the time taken for it to reach the top of the window with this velocity
Let h be the height above the top of the window
When a conductor is passed through a magnetic field, a current is induced in the CONDUCTOR.
This process is called electromagnetic induction. Electromagnetic induction involves the production of electromotive force in an electrical conductor in a magnetic field. Electromagnetic induction can be generated using two different methods:
1. By keeping the electric conductor in a moving magnetic field.
2. By keeping the electric conductor in constant motion in a static magnetic field.
Answer:
i might know the answer to this, so can you help me with my question too?
Explanation:
the cycle of the Moon through all its phases
Explanation:
The cycle of the Moon through all its phases is closely related to the unit of time that humans call month.
It takes 27 days for the moon to complete its orbit around the earth and this is equivalent to a month.
The moon is the earth's natural satellite and it revolves round it in every 27 days.
The moon passes through its different phases within this time period.
