Our Earth budget is how much energy we receive from the sun.
So the best answer is A
Answer:
15) C
14) When the density of the object is less than that of the liquid, it floats on the liquid because the upthrust or buoyant force of water is more than the gravity acting on the object. so option A is the best choice out of all.
Explanation:
Answer:
Rp = 10 Ohms; I = 0.9 Amps
Explanation:
Since, there are two resistors each with 20Ω connected in parallel, the total resistance of the combination (Rp) of the circuit is as follows:
i.e 1/Rp = (1/R1 + 1/R2)
1/Rp = (1/20Ω + 1/20Ω)
1/Rp = (1 + 1)/20Ω
1/Rp = 2/20Ω
1/Rp = 1/10Ω
To get the value of Rp, cross multiply
Rp x 1 = 10Ω x 1
Rp = 10Ω
Apply the formula
Voltage V = Current I x Total resistance Rp
I = V/Rp
I = 9V/10Ω
I = 0.9 Amps
Thus, the total resistance is 10 Ohms, the current through the ammeter is 0.9 Amps
Upper mantle
The theory of the plate tectonics uses the convection cells in the upper mantle layer as the foundation for the movement of the continents.
To put it simple the process is explained like the convection cells create a lot of pressure, that pressure, supported by the high temperatures and magma, influence the crust above, and manage to crack it on certain places. As the crust cracks, it becomes a separate entity, and under the enormous force from bellow it slowly moves into a particular direction, and that is actually the movement of the tectonic plates.
Answer:
2.52N
Explanation:
according to law of moments ,
F1L1=F2L2 ,where the forces are in equilibrium .
0.85(44.5)= 15F2
that is , taking their distances from 50cm point
37 .825=15F2
37.825÷15= F2
2.52N = F2
