Answer:

A change in pressure

Explanation:

This is because, the deeper you dive, the height of water above you creates a pressure on you. So, as the depth increases, the height of water increases, thus its weight on you, thus its pressure on you also.

Also, as you gain altitude as you climb a mountain, the height of air above you decreases. This thereby decreases the weight of air above you thus, decreasing the pressure of air on you.

So, in both cases, there is a change in pressure as height or depth changes. An increase in height results in decreased pressure and an increases in depth results in increased pressure.

In practice, if a voltmeter was connected across any combination of the terminals, the potential difference would be less than w

VladimirAG [237]

Answer:

This difference is kept to a minimum because the resistance in transformers is a few tens of ohms and the resistance of modern voltmeters is of the order of MΩ.

Explanation:

A voltmeter is built by a galvanometer and a resistance in series, this set is connected in parallel to the resistance where the voltage is to be measured, therefore the voltage is divided between the voltmeter and the element to be measured, consequently the measured voltage It is less than the calculated one, since for them the resistance of the voltmeter is assumed infinite.

This difference is kept to a minimum because the resistance in transformers is a few tens of ohms and the resistance of modern voltmeters is of the order of MΩ.

Predict the precipitate when the double replacement reaction occurs: Ca(NO3)2(aq) + Na2CO3(aq) →

taurus [48]

Ca(NO3)2(aq) + Na2CO3(aq) → 2NaNO3 + CaCO3⬇. NaNO3 is solution so CaCO3 is the precipitate formed.

Explain why a cow that touches an electric fence experiences a mild shock

Minchanka [31]

The voltage exists between the fence and the ground. The cow is grounded. The cow is touching the ground, completing the circuit of electricity. When the cow comes into contact with the fence, it becomes an electric ground which sends an electric current into the cow, through the cow, and into the ground. The pain experienced from the shock is due to the current that flows through the cow.

Suppose a woman raises a 65 N object in 2m in 4 seconds.

Novosadov [1.4K]

Answer:

$\huge\boxed{\sf P.E = 130\ Joules}$

$\huge\boxed{\sf P = 32.5\ Watts}$

Explanation:

Given Data:

Weight = W = 65 N

Height = h = 2 m

Time = t = 4 secs

Required:

Power = P = ?

Work Done in the form of Potential Energy = P.E. = ?

Formula:

P.E. = Wh

P = P.E. / t

Solution:

P.E. = (65)(2)

P.E = 130 Joules

P = P.E. / t

P = 130 / 4

P = 32.5 Watts

$\rule[225]{225}{2}$
