Answer: a circluar motion.
Explanation:
Answer:
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease.
Explanation:
= Wavelength
f = Frequency
Velocity
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease. This is true for any wave whether sound or electromagnetic.
Vector quantites: it is a quantity which has both direction and magnitude.
for example. force which has direction and magnitude both.
scalar quantities: it is a quantity which has magnitude only.
for example. age it has only magnitude.
Answer:
Explanation:
Kinetic energy of block will be converted into heat energy by friction .
Heat energy produced = 1/2 m v²
= .5 x 4.8 x 1.2²
= 3.456 J
85% of energy is converted into heat energy , so heat energy produced
= .85 x 3.456 = 2.9376 J .
If Q heat is given to m mass of object having s as specific heat and Δt is increase in temperature
Q = msΔt
specific heat of iron s = 462 J / kg C
Putting the values ,
2.9376 = 4.8 x 462 x Δt
Δt = 13.24 x 10⁻⁴ ⁰C.
