Pressure = height x density x gravity = 2 x 1000 x 9.8 = 19600 Pascal ( N / m^2 )
The total distance travelled is 307.5 miles.
<h3>What is the distance covered?</h3>
We know that the distance covered can be obtained from the formula from speed since the motion all took place in the same direction.
Speed = distance/time
distance = speed * time
In the first case;
Distance = 35 mph * 2.5 hours = 87.5 miles
In the second case;
Distance = 55 mph * 4.0 hours = 220 miles
Total distance = 87.5 miles + 220 miles = 307.5 miles
Hence the total distance travelled is 307.5 miles.

Answer:
1. Speed=0
2. 2.46 s
3.30.1 m
4. 22.0 m
5.1.004 s
Explanation:
We are given that
Initial speed of blue ball, u=24.1 m/s
Height of blue ball from ground y_0=0.5 m
Initial speed of red ball , u'=7.2 m/s
Height of red from ground=y'0=32 m
Gravity, g=
1.When the ball reaches its maximum height then the speed of the blue ball is zero.
2.v=0

Using the formula and substitute the values

Where g is negative because motion of ball is against gravity


3.
Using the formula


4.Time of flight for red ball=3.77-2.9=0.87s


Hence, the height of red ball 3.77 s after the blue ball is 22.0 m.
5.According to question






Hence, 1.004 s after the blue ball is thrown are the two balls in the air at the same height.
The holographic principle is a principle of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region preferably a light like boundary like a gravitational horizon.
