Time taken by the car to travel 300 miles is 4.615 hours.
<h3>What is speed?</h3>
The speed of any moving object is the ratio of the distance traveled and the time taken to cover that distance.
Given is the distance d = 300 miles and the speed s = 65 miles/hour, then the time taken t will be
s=d/t
65 = 300/t
t= 4.615 hours
Thus, time taken by the car to travel 300 miles is 4.615 hours.

magnetic domain is a region within a magnetic material in which the magnetization is in a uniform direction. This means that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.
Answer:
Explanation:
acceleration of an object on an inclined plane due to gravitational pull
= g sinθ . This acceleration is irrespective of mass of the object coming down . It only depends on the inclination .
If θ is larger , sinθ will be larger hence gravitational acceleration on inclined surface will be greater . It happens so because a component of weight mg is acting on the body . This component is mgsinθ . The other component mgcosθ acts perpendicular to surface hence it does not contribute to its acceleration .
acceleration produced = force / mass
= mgsinθ / m
= gsinθ .
in the given case , the inclination of plane with mass m₁ is less , hence its downward acceleration will be lesser as compared with the acceleration of m₂ which is put on a surface with greater inclination .
Answer:
Velocity = 94.85m/s
Explanation:
<u>Given the following data ;</u>
Height = 1200m
Vertical distance = 1050m
To find the time, we would use the second equation of motion;
Substituting into the equation, we have;
t = 11.07 secs
To find the velocity;
Mathematically, velocity is given by the equation;
Substituting into the above equation;
Velocity = 94.85m/s
Therefore, the velocity of the water above 1050 m over the sea level is 94.85m/s.
Answer:
Energy
A wave is a disturbance that carries energy from one place to another through matter and space.
Explanation:
A wave can be defined as a form of disturbance that carries energy from one place to another through matter and space.
The energy of wave depends on the frequency of the wave and the wavelength (lambda) of that particular wave.
Mathematically,
V = f × lambda
