Explanation:
Solution,
Given:-
- Length=10 cm
- Width= 20 cm
- Height= 5 cm
- Volume =?
Now,
By using the formula of volume of a cuboid, we have
- volume=length×width×height
- volume=10 cm×20 cm×5 cm
- volume=1000 cm³
- volume= 1×10×10×10×10 cm³
- volume=(1×10⁴) cm³
Hence, last option is the correct answer.
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
Answer:
(A)chimney
Explanation:
bc all the smoke is going into the chimney
Answer:
34.62m/s^2
Explanation:
Force = mass x acceleration
Given
Force = 1800N
Mass = 52kg
Therefore
1800 = 52 x a
Divide both sides by 52
1800/52 = 52/52 x a
34.62 = a
a = 34.62m/s^2
