A body is uniformly accelerated from rest to a final velocity of 100m/s in 10 seconds.Calculate the distance covered
Answer:
Solution s =ut + ½ at 2 = 0×10 + ½ × 10×10 2 = 1000/2=500 m
Explanation:
The body is accelerating from stationary to a velocity of 100 m/s within 10 seconds. Thus, the distance covered is 500 m.
What is acceleration?Acceleration of a moving body is the rate of change in its velocity. Acceleration is a vector quantity having both magnitude and direction. The change in magnitude or direction or both in velocity causes an acceleration in the moving body.
The relation between distance with the velocity, acceleration and time is given as :
s = ut + 1/2 at²
The initial velocity u = 0 here
v = 100 m/s
t = 10 seconds.
acceleration = 100 /10 = 10 m/s²
Then the distance covered is calculated as follows:
s = 1/2 at²
= 1/2 10 m/s²× 10²
= 500 m
Therefore, the distance covered by the body is 500 m.

Visible light has a range of wavelengths from about 400-750 nm. Which of these wavelengths is
most likely seen as the color red?
Answer:
600-750
Explanation:
The red color in the visible region lies in the wavelength of 600 – 750 nm. The visible light spectrum is the fraction of the spectrum that is visible to humans.
What is wavelength ?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The length of a wave is measured in its propagation direction. The wavelength is measured in meters, centimeters, nanometers, and other units since it is a distance measurement.
The portion of the spectrum visible to the human light is known as the visible light Spectrum.
Visible light has a range of wavelengths from about 400-750 nm. The red color in the visible region lies in the wavelength of 600 – 750 nm.

Which graph shows an object with constant acceleration?
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 10, and velocity in meters per second on the y axis, numbered 0 to 50. A line starts at the origin and goes to (4, 40), then a line from (4, 40) to (9, 40) and a line from (9, 40) to (10, 0).
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, and velocity in meters per second on the y axis, numbered 0 to 10. A line starts at (0, 10) and ends at (5, 0).
A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, velocity in meters per second on the y axis, numbered 0 to 35. A curved line starts at the origin and arcs up to (4.3, 35).
The graph in the question that represents an object with constant acceleration is : Graph A
Description of constant accelerationAcceleration is the change in velocity with time. For graph A the acceleration remained constant as the velocity of the object did not change with the change in time. As the time changes from 4 to 9 seconds the velocity of the object remained at 40 before decelerating to 0. This shows that the acceleration of the object was constant.
Hence we can conclude that The graph that shows an object with constant acceleration is : Graph A

For an erect object is 50 cm from a concave mirror of radius 60 cm. In the situation above, the object is moved to a new position, the new object distance is mathematically given as
u = -18cm
What is the new object distance?
Generally, the equation for magnification is mathematically given as
1/f = 1/v +1/u
therefore,
-1/30 = 1/v + 1/u
v = -2.5u
Hence,
-1/30 = -1/2.5u + 1/u
-1/30 = (3/5)u
u = -18
In conclusion, the new object distance is
u = -18cm

thermal energy to one with lower thermal energy;
B. Heat flows from an object at higher tem-

C. Heat flows from an object in liquid state
to an object in solid state.
Which statements are true?
Answer:The heat flows from an object at a higher temperature to the object at a lower temperature. Thus the option A is correct.
Explanation:What is heat flow?
The flow of heat is the transfer of heat that concerns its generation, use and conversion, and exchange.The heat flow follows the laws of the thermodynamics. Heat will flow from the body that is at a higher temperature and will move towards a body of a lower temperature. Thereby maintaining an equilibrium state. As energy is needed to warm or heat up the cold body there is an exchange of energy that takes place.
