Answer:
Velocity
Explanation:
You would be describing the velocity of the car.
Velocity in physics is defined as Vector quantity that describes the displacement of an object with respect to the time it takes to attain it. Displacement is the addition of direction to the speed of an object. The displacement is noted in the question, "traveling eastward". While it is stated that the car travels at 44.704 m/s. Ordinarily, it would have been tagged speed, if not for the direction added to it which makes it velocity.
I hope you understand.
Answer:
q = 5 C
Explanation:
The electric field is defined as the force experienced by a unit charge when it is brought into the field. Hence, the formula used to find the electrical field is given as follows:
E = F/q
where,
E = Electric Field Magnitude = 10 N/C
F = Force Experienced by the test charge = 50 N
q = Magnitude of the Charge = ?
Therefore,
10 N/C = 50 N/q
q = 50 N/(10 N/C)
Therefore,
<u>q = 5 C</u>
Answer:
work done is 470400 J
Explanation:
given data
long = 3 m
wide = 2 m
deep = 4 m
density = 1000 kg/m³
to find out
Find the amount of work in joules
solution
we know here volume = area × length
so
area = 0.5 ×base×height
area = 0.5 ×2×4
area = 4 m²
so volume = 4 × 3 = 12 m³
and
weight of water = volume ×density×g
weight = 12 × 1000 × 9.8
weight = 117600 N
so
work done = weight × height
work done = 117600× 4
work done = 470400 J
Answer:
The heat rejected is 146J.
The work done by the engine is 54J.
The thermal efficiency is 0.27
Explanation:
The efficiency of the carnot engine, which is working between a hot source at a temperature and a cold source at a temperature , is given by:
The normal boiling point of water is 373 K. ()
The temperature of triple point of water is 273.15 K ()
Answer:
wind speed i think where i live?
