A. Elements on the bottom left
B. Elements on the bottom right
C. Elements on the top right
D. Elements on the top left

ANSWER:

(1) Electric motors

(2) Batteries

Answer:Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

energy = (1/2)*m*(v^2)

Powering Your Home: Understanding Energy Resources in Dubai, United Arab Emirates

Dubai, one of the seven emirates of the United Arab Emirates, is a rapidly growing city with a population of over 3.3 million people. With the increase in population and development, the demand for electricity has also risen significantly. Have you ever wondered where the electricity that powers your home comes from? In this handout, we will provide you with information about the energy resources used to power the electrical grid in Dubai.

Nonrenewable Resources:

Dubai relies heavily on nonrenewable resources such as natural gas and oil to generate electricity. As per Dubai Electricity and Water Authority (DEWA), in 2020, 94% of the electricity generated in Dubai came from natural gas and 6% from coal.

Renewable Resources:

Dubai has been working to diversify its energy mix by investing in renewable resources. According to DEWA, 6% of Dubai's electricity in 2020 was generated from renewable sources, such as solar and waste-to-energy. DEWA has set a target to increase the share of renewable energy in Dubai's energy mix to 75% by 2050.

Nuclear Energy:

Dubai is also investing in nuclear energy to diversify its energy mix. The first nuclear power plant in the UAE, the Barakah Nuclear Energy Plant, started operations in 2020. It is expected to generate 5.6 GW of electricity and will contribute to reducing carbon emissions.

Most Used Renewable Resource:

Dubai has the world's largest single-site solar energy project, the Mohammed bin Rashid Al Maktoum Solar Park. It is a key component of Dubai's clean energy strategy, and its capacity is expected to reach 5 GW by 2030. The solar park uses photovoltaic solar panels to convert sunlight into electricity.

Interesting Fact:

Dubai is home to the world's tallest building, the Burj Khalifa, which has been designed to be energy-efficient. It uses a combination of technologies such as a high-performance glass facade, an efficient air-conditioning system, and a double-decker elevator system that reduces energy consumption by 20%.

Conclusion:

Dubai's energy mix is currently dominated by nonrenewable resources, with natural gas being the primary source of electricity generation. However, the city is making significant strides to increase the share of renewable energy and diversify its energy mix. By investing in nuclear energy and the Mohammed bin Rashid Al Maktoum Solar Park, Dubai is working towards achieving its goal of becoming a sustainable city and reducing its carbon footprint.

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

Answer:

The maximum depth of the water at the place is 6.0 meters.

Given the tidal range and average depth, it is to be noted that the maximum depth of the water at the place, is 6.0 meters.

The tidal range is the successive difference between tide highs and lows, which is a sinusoidal pattern. On the basis of the above, it is correct to state that the tidal range is twice of the amplitude of the tide level.

That is:

The Amplitude of the tide, A = 2.0/2m = 1m

The maximum depth at the place, therefore, is given as:


D\(_{max}\) = A + D\(_{ave}\)

Hence,

D\(_{max}\) = 1.0 + 5.0 = 6.0

Thus, it is correct to state that the Maximum Depth (D\(_{max}\)) = 6.0 Meters.

The bottom wave has a greater frequency.

Explanation:

1. Waves with a low frequency have a longer wavelength.

2. Waves with a high/great frequency have a shorter wavelength.

The bottom wave has a greater frequency. So, the second option is correct.

Frequency of a wave is defined as the number of oscillations the wave completes in one second.

Here,

The diagrams of two waves are represented. The propagation of wave from the time zero to one second is given.

From the first diagram,

The wave is travelling from point a at t =  0 and reached at the point b at t = 1 s. This means in a time duration of 1 second, it has travelled a distance ab from a to b. The time taken for one oscillation to complete is called the time period. In the diagram, the number of waves passing in one seconds can be calculated. A few number of waves passed in one second.

From the second diagram,

The wave is travelling from the point a to point b in a time duration of one second. When compared to the top wave, the time taken for one wave to complete is lesser for the bottom wave. That means the time period is lesser than the top wave. In the diagram, it can be seen that, the number waves that has been completed in the one second is very high compared to that of the top wave. That means the bottom wave has higher frequency than that of the top wave.

Hence,

The bottom wave has a greater frequency.

Answer:

Look at explanation

Explanation:

One of the easier ways to define wave motion is the continuous movement of particles. When we have a rope for example and whip it, the first particle bumps into the second one then into the third and so on and so forth until the end of the rope. Particles can only move up and down or left and right and the vibration caused by each particle is what sets off the wave motion.

The work input = Fi × di

To solve for work input, you need to know the force acting on an object and the distance it moves in the direction of the force. Work input is defined as the product of force and distance, given by the formula:

Work Input = Force × Distance × cosθ

Where θ is the angle between the force vector and the direction of motion. If the force is applied in the direction of motion, then θ = 0 and cosθ = 1, so the formula simplifies to:

Work Input = Force × Distance

For example, if you are pushing a box with a force of 50 newtons over a distance of 10 meters, the work input would be:

Work Input = 50 N × 10 m × cos(0°) = 500 Joules

Answer:

, if we see we are considering this initial mass of this in this particular case, the initial mass of substantiated- or we can say, mercury oxide heated, it is, we can say, 27 grains. So this is the initial mass which is heated here. It is like this and what we can say we can consider this consent, passion of mass, so consummation of mass. We are looking here, the log, the conservation of the mass, so conservation of mass state at mass. It is always converted, but if it's not the case, we can also modify it it through mass and energy. They are combined converted or we can say, mass energy equivalence here so mass. It is confirmed in this case, so we can say, but here it is said that initially mass was 27 gram and finally mass was 25 gram. So but as we know, mass it is conserved mass, it is always conserved, so if the mass it is conserved, we should say this thing that the lost in the 2 gram weight must be due to the evaporation or we can say formation of the gases which Have been escaped, that is why it cannot be recorded, so we can say 2 gramos in the mass to the escape of the gas, or we can say evaporation.
