a stone block has length of 90cm and breadth of 25cm . if its mass is 250kg. find the pressure given by it on the ground.

Here,

Length(l) = 90 cm

converting onto metre, 90/100= 0.9m

breadth(b)=25 cm

converting into metre,

25/100= 0.25m

mass(M)= 250 kg

acceleration due to gravity (g)= 10 m/s2

Pressure(P)= ?

We know,

P=F/A

or,P=M*G/L*B

or, P= 250*10/0.25*0.9

or.P=2500/0.225

or,P=11111.11111

Therefore, the the stone block applies a pressure of 11111.11111 pascal

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
