Answer:
your answer will be 320kg that would be the pressure at the bottom surface of the block
ANSWER:
C. Small, minimize
Hope it helps u!
Answer:
The weight if the block is 10Newtons
Explanation:
The weight of any object is quantity of matter the object contains and it is always acting downwards on such body. This shows that the object is under the influence of gravity.
The weight of an object is calculated as mass of the object × its acceleration due to gravity
W = mg
Give the mass of the brick to be 1kg
g is the acceleration due to gravity = 10m/s²
Weight of the object = 1 × 10
= 10kgm/s² or 10Newtons
The distance covered by Arthur is
3t
The distance covered by Betty from where Arthur started is
100 - 2t
They meet each other when this distance is equal
3t = 100 - 2t
t = 20 s
Since the dog has a constant speed of 5m/s, the distance that Spot has run is
5 m/s (20s) = 100 m
Answer:
Ultra violet rays and infrared rays
Explanation:
The electromagnetic radiation in the order of increasing wavelength is given as
Gamma rays
X rays
Ultra violet rays
Visible radiation
Infrared rays
Microwaves
radiowaves
So, the radiations having wavelength more than the visible radiation are infrared radiations and the radiations which having the wavelength less then the visible radiation is Ultraviolet rays.
So, we observe ultra violet radiations and infrared radiations.
