Energy is a property that is capable of causing changes in a matter, it is measured in joules. Chemical energy is the energy derived from the chemical bonding between atoms. In this case, petroleum and biomass have energy stored in form of chemical energy. Energy can be stored and can never be destroyed or created but is transformed from one form to another.

A 6.00 kg object is lifted vertically through a distance of 5.25 m by a light string under a tension of 80.0 N. Find: (2 marks)

jeka57 [31]

Explanation:

It is given that,

Mas of the object, m = 6 kg

It is lifted through a distance, h = 5.25 m

Tension in the string, T = 80 N

(a) By considering the free body diagram of the object, the forces can be equated as :

$T-mg=ma$

$a=\dfrac{T-mg}{m}$

$a=\dfrac{80-6\times 9.8}{6}$

$a=3.33\ m/s^2$

Work done by tension, $W_t=F\times h$

$W_t=80\times 5.25$

$W_t=420\ J$

(b) Work done by gravity, $W_g=mgh$

$W_g=6\times 9.8\times 5.25$

$W_g=308.7\ J$

(c) Let v is the final speed of the object and u = 0

$v=\sqrt{2ah}$

$v=\sqrt{2\times 3.33\times 5.25}$

v = 5.91 m/s

Hence, this is the required solution.

At locations A and B, the electric potential has the values VA=1.51 VVA=1.51 V and VB=5.81 V,VB=5.81 V, respectively. A proton r

Oksana_A [137]

Answer:

For proton:

A. The proton is released from Vb (highest potential)

B. v = 2.9x10⁴ m/s

For electron:

A. The electron is released from Va (lowest potential)

B. v = 1.2x10⁶ m/s

Explanation:

For a proton we have:

A. To find the origin from which the proton was released we need to remember that in a potential difference, a proton moves from the highest potential to the lowest potential.

Having that:

Va = 1.51 V and Vb = 5.81 V

We can see that the proton moves from Vb to Va, hence the proton was released from Vb.

B. We now that the work done by an electric field is given by:

$W = \Delta Vq$ (1)
