If you have an oily or saturated absorbent pad after refueling at a marina fuel dock then the best thing to do with it is:

1) To clean up the spills of fuel immediately with oily or saturated absorbent pad.

2) Moreover, the interior parts of the fuel which are in contact with the fuel should be wiped with the saturated absorbent pad.

In an inelastic collision involving an isolated system, the final total momentum is

Aleksandr-060686 [28]

Answer: B) exactly the same as the initial momentum.

Explanation:

An inelastic collision occurs when the elements that collide remain together after the collision, and althogh the kinetic energy is not conserved because is transformed into other kinds of energy (thermal energy, for example), the linear momentum does.

This means the initial momentum before the collision will be equal to the final momentum after the collision:

$p_{o}=p_{f}$

Daisy walks across a force platform, and forces exerted by her foot during a step are recorded. The peak velocity reaction force

Len [333]

Answer:

(a). The resultant of these forces is 1216.55 N.

(b). The direction of the resultant forces is 80.53°.

Explanation:

Given that,

First force = 1200 N

Second force = 200 N

(a). We need to calculate the resultant of these forces

Using cosine law

$F=\sqrt{F_{1}^2+F_{2}^2+2F_{1}F_{2}\cos\theta}$

Put the value into the formula

$F=\sqrt{1200^2+200^2+2\times1200\times200\cos90}$

$F=\sqrt{1200^2+200^2}$

$F= 1216.55\ N$

The resultant of these forces is 1216.55 N.

(b). We need to calculate the direction of the resultant forces

Using formula of direction

$\tan\alpha=\dfrac{F_{1}}{F_{2}}$

Put the value into the formula

$\alpha=\tan^{-1}(\dfrac{1200}{200})$

$\alpha=80.53^{\circ}$

Hence, (a). The resultant of these forces is 1216.55 N.

(b). The direction of the resultant forces is 80.53°.

If a 12 kg cat is sitting 5 m up in a tree, how much PE does it have?

Helen [10]

Answer:

588 J

Explanation:

PE (potential energy) = (mass) x (gravity) x (height)

mass = 12 kg

gravity = 9.8m/s^2

height = 5 m

PE = (12) x (9.8) x (5) = 588 J (Joules)

Which of the following best describes a substance in which the temperature remains constant while at the same time it is experie

katen-ka-za [31]

Answer:

The right option is (d) substance undergoing a change of state

Explanation:

Latent Heat: Latent heat is the heat required to change the state of a substance without change in temperature. Latent heat is also known as hidden heat because the heat is not visible. The unit is Joules (J).

Latent heat is divided into two:

⇒ Latent Heat of fusion

⇒ Latent Heat of vaporization.

Latent Heat of fusion: This is the heat energy required to convert a substance from its solid form to its liquid form without change in temperature. E.g (Ice) When ice is heated, its temperature rise steadily until a certain temperature is reached when the solid begins to melts.

Latent Heat of vaporization: This is the heat required to change a liquid substance to vapor without a change in temperature. The latent heat depend on the mass of the liquid and the nature of the liquid. E.g When water is heated from a known temperature its boiling point (100°C) When more heat is supplied to its boiling temperature, it continue to boil without a change in temperature.

From The above, Latent heat brings about a change of state of a substance at a steady temperature.

The right option is (d) substance undergoing a change of state
