Answer:
The length of line is 78 cm or 0.78 m.
Explanation:
initial reading 2 mark
final reading 80 cm
The length of the line
= final reading - initial reading
= 80 - 2
= 78 cm
1 cm = 0.01 m
So, 78 cm = 0.78 m
Answer:
Quick action was in this as a thought of he knew he could die from this
Answer:
350Joules
Explanation:
According to law of Conservation of energy, the amount of energy at the used up at the start is equal to that at the end.
The initial energy used up is gravitational potential energy
Final energy at the lowest point is kinetic energy.
If the energy is conserved then it means energy is not used up during the process hence;
Initial Potential energy = Final kinetic energy
If the gravitational potential energy is 350Joules then her final kinetic energy at the lowest point will also be 350Joules
Answer:
Explanation:
unbalance force can be defined as the force that makes object slow up or down, in order words unbalanced force can be defined as anything that can alter the state of motion of an object.
an example of an unbalanced force is likened to a situation of someone inside a lift going for a meeting at the top floor, the force which propels the lift upward is unbalanced, because it is greater than the force acting on the lift.
Answer:
The transformation went from a gas to a solid which is a Deposition
Explanation:
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
