The distance covered by the car is 39.9 m
Explanation:
Since the car is slowing at constant rate, it means that its acceleration is constant, therefore we can solve the problem by using the following suvat equation:
where
s is the distance covered
u is the initial velocity
v is the final velocity
t is the time elapsed
For the car in this problem, we have
u = 19 m/s (initial velocity)
v = 0 (final velocity)
t = 4.2 s (time elapsed)
Therefore, the distance covered is

Answer:
Explanation:
= Rate at which the distance between A and starting point of B is changing = -20 km/h
= Rate at which the distance of B is changing = 15 km/h
= Rate at which the distance between A and B is changing
Time after which the rate at which the distance between A and B is changing is 4 hours
Distance covered by A in 4 hours =
a = Distance remaining to the start point of B =
b = Distance covered by B in 4 hours =
Distance between A and B after 4 hours
Differentiating with respect to time we get
The rate at which the distance between the ships is changing at 4 PM is .
Answer:
Answer is A) Fermi
Explanation:
Fermi is the expressive unit for nuclear sizes. Fermi = 10^-15 meter.
Answer:
They include;
1. Earthquakes
2. Floods
3. Hurricane
4. Landslide
5. Tsunami
6. Tornadoes
Explanation:
Emergencies are sudden disasters that occur occasionally and unexpectedly, resulting in massive destruction of lives and property, and which require prompt actions to resolve. When some of these emergency situations occur, the electric grids could fail, resulting in a power outage in the affected town or community. Rescue workers might then find communication difficult because they cannot get energy to their electrical devices.
Examples of emergency situations that could have this type of effect include; Earthquakes, Floods, Hurricane, Landslide, Tsunami, and Tornadoes.
