Over time, the types of technology can vary and be improved upon so that more advanced techniques become more valued. This could be the situation with mining whereby back in the 1500's in underground mines the rock was broken by fire setting ie lighting a fire below the rock face to heat up the rock and then throwing cold water on it to crack it, so that it could be dug by hand. With the advent of explosives, this all changed so that the rock could be blasted. The increase in advance rates for an underground heading have thus gone from 5-20 feet per month to up to 300meters (984 ft) per month for a 24/7 mining operation, which is a huge improvement.

ANSWER: Over the years, technology has advanced a lot and has made our lives simpler. We have been seen technological advancements in almost everywhere starting from our workplace to our homes and also at streets.

A classic example of technological advancement can be how people communicate to each other. People previously had only the option of railroads for traveling purposes to distant places. Later, with the introduction of airline industry, people started traveling across countries for many reasons like for business meetings, meeting a relative etc. The entire crowd of business travelers shifted to other technological innovation to save their precious time and money. The technology that replaced the need to travel far across countries was Video Conferencing. A huge number of business travelers opted for this innovation in technology. This advancement also suppressed the cell phone industry which only allowed voice calls at that time.

Also, people used to write mails and used to send telegrams. The telephone came into scenario and gave people an option to communicate faster which previously used to take days to send a message. Then in the 1990's, the email was introduced and gave everyone a platform to send instant and free messages. This gained popularity in 1996-97 with Hotmail services. Later on, it got updated with instant messaging services across the globe like Whatsapp services. Thus, this is how technology varies and are valued accordingly by their usage in that era and the types of technologies grew independently in their respective fields and replaced the outdated ones.

A person strikes a ball with a bat. The temperature of the ball increases by 0.06ᵒC. What accounts for the increase?
marusya05 [52]

The increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.

Kinetic energy of a particle is directly proportional to its temperature.

A ball initially at rest acquires kinetic energy when an external force is applied to it. As the person strikes the ball with a bat, the ball gains momentum which increases its kinetic energy of the ball.

Temperature on the other hand, is the measure of the average kinetic energy of a particle. Consequently, as the kinetic energy of the ball increases, the temperature of the ball increases as well.

Thus, we can conclude that the increase in the average kinetic energy of the ball causes the increase in the temperature of the ball.

To change a tire, you need to use a jack to raise one corner of your car. While doing so, you happen to notice that pushing the
Alja [10]

Answer:

Explanation:

The energy lost by the handle in lowering is equal to the energy gained by the car in raising the height.

As the mass of car is much more as compared to the jack, so the height raised by the car is very small as compared to the handle of jack.

A camcorder has a power rating of 10 watts. If the output voltage from its battery is 3 volts, what current does it use?
Gemiola [76]
The power is calculated using the following rule:
Power = voltage * current
We are given that:
power = 10 watts
voltage = 3 volts

Substitute with the givens in the above equation to get the value of the current as follows:
P = V*I
10 = 3*I
current (I) = 10/3 amperes

Rearrange the equation current = voltage/resistance to express resistance in terms of current and voltage. Then solve the follow
MissTica

Answer:

Resistance, R = 13 ohms

Explanation:

The Ohm's law gives the direct relationship between the voltage, current and the resistance of the device. The relation is as follows :

V=IR

Where

I is the current

r is the resistance

The value of resistance is given by :

R=\dfrac{V}{I}

According to given data,

Voltage of the circuit, V = 130 V

Current rating of the circuit, I = 10 A

Resistance of the device,

R=\dfrac{130\ V}{10\ A}

R = 13 ohms

So, the resistance of the device is 13 ohms. Hence, this is the required solution.
