Why was John Paul Jones's victory important in the war? His victory increased France's confidence in the skill of the Continental navy. His victory against a large warship dealt a blow to the Spanish navy. His victory against a superior British foe inspired the American troops.
Answer:
C. His victory against a superior British foe inspired the American troops.
Explanation:
John Paul Jones is considered the hero in the Revolutionary War. He is known as the Father of the US Navy.
In the Revolutionary War, Jones sided with the American colonists against the British and took hold of naval ships. In 1779, when the British warship Serapis was in conflict with the American warship Bon Homme Richard, Jones plugged the American warship with the Britisher's warship and tossed a grenade into the opponent warship. Thus when Jones was victorious in the war, this boosted the American spirits for the war.

A bicyclist steadily speeds up from rest to 11.0m/s during a 5.50s time interval. Determine all unknowns and answer the following questions. What is the magnitude of the bicyclist's acceleration? How far did the bicyclist travel during this time?
Explanation:
acceleration is 2 m/s^2
v-u/t
distance travelled is 30.25 meter
(v^2-u^2)/2a
11*11/2*2
121/4
30.25 m
The acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
We have a bicyclist.
We have to calculate the acceleration and the total distance travelled by the bicyclist.
State the three equations of motion.The three equations of motion are -
v = u + at
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
v² - u² = 2aS
According to the question -
u = 0 m/s
v = 11 m/s
t = 5.5 s
Therefore -
For acceleration -
v = u + at
On solving -
11 = 0 + 5.5 a
5.5a = 11
a = 11 / 5.5 = 2 m/s²
For total distance covered -
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
On solving -
S = 0 + 0.5 x 2 x 5.5 x 5.5 = 30.25 meters.
Hence, the acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.

A train moves at 300 km/h. How far will it go in 5 hours?
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p

A meterologist made these observations one day:

• In the afternoon, an ocean wave hit the shorlinie every 30 seconds.
Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.
Answer:
They transfered more energy in the morning.
Explanation:
This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with the waves. They have more energy, so they can crash aganst the shore more!

A train reaches a speed of 35.0 m/s after accelerating at a rate of 5.00 m/s2 over a distance of 40.0 m. What was the train’s initial speed?
Answer:
Initial velocity, U = 28.73m/s
Explanation:
Given the following data;
Final velocity, V = 35m/s
Acceleration, a = 5m/s²
Distance, S = 40m
To find the initial velocity (U), we would use the third equation of motion.
V² = U² + 2aS
Where;
V represents the final velocity measured in meter per seconds.
U represents the initial velocity measured in meter per seconds.
a represents acceleration measured in meters per seconds square.
S represents the displacement measured in meters.
Substituting into the equation, we have;
35² = U + 2*5*40
1225 = U² + 400
U² = 1225 - 400
U² = 825
Taking the square root of both sides, we have;
Initial velocity, U = 28.73m/s

1. A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the
table.
A. What is the vertical velocity of the ball just before it hits the floor?
d. What is the horizontal velocity of the ball just before it hits the floor
Answer:
5.55m/s
Explanation:
The vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
Which type of motion is projectile motion?
Projectile motion is an example of two dimensional motion.
Given is a ball rolls off a 1 m high table and lands on the floor 3 m away from the table.
Using the second equation of motion for the vertical motion -
S = ut + 1/2at²
S = 0 + 1/2at²
S = 1/2at²
t²= 2S/a
t² = (2 x 1)/9.8
t² = 2/9.8
t² = 0.2040
t = 0.451
Now, the vertical velocity of the ball just before it hits the floor -
v = u + at
v = 0 + at
v = at
v = 9.8 x 0.451
[v] = 4.42 m/s
Now, using the second equation of motion for horizontal direction -
S = ut + 1/2at²
S = ut + 0
3 = u x 0.451
u = 3/0.451
[u] = 6.6 m/s
Which is also the horizontal velocity of the ball just before it hits the floor.
Therefore, the vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
