Answer:

The found value of r is:

r = 94.7

Explanation:

We know that

cosθ = Base / Hypotenuse

θ is the always the angle between base and hypotenuse

In this right angles triangle, the angle θ is given 63°.

Which means that the Base is 43 and the hypotenuse is r

Base = 43

Hypotenuse = r

Substitute θ=63°, Base = 43 and hypotenuse = r in the formula of cosθ mentioned above:

cos 63° = 43/r

Rearrange

r = 43/cos63°

r = 43/0.454

r= 94.7

Answer:

Water vapor

Explanation:

because water vapor is gas and gas particles move faster than solid particles (which stick together) and water particles ( with a somewhat normal movement) and the faster the particle, the hotter the substance is. With that being said C is the correct answer.

Curling is a sport in which players slide stones across a  distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side.  There are two  brigades. Each  platoon is trying to keep the other  platoon's  monuments down from the target by knocking their  monuments out of the way.

Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object."  This relates to the formula F =  ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

Answers:

Part One: Elastic Potential Energy

Part Two: Potential energy converted to kinetic energy when the ball started moving down the ramp.

Explanation:

Part One: The ball is not moving, therefore there is no Kinetic energy. The ball does not involve chemicals, so there is no Chemical Energy. By the process of elimination, you'll gather that there is potential energy to be had.

Part Two: Remember when we talked about the ball being still, and not moving? Well here's where it does. The potential energy has now turned into kinetic energy as it begins to roll down the ramp. The steeper the ramp the faster the kinetic energy will build.

big brain

Answer:

No, I don't agree with the friend.

Explanation:

I don't agree because the energy doesn't just "disappear it's converted to kinetic energy. due to the friction some of the energy in the system is converted to heat energy making it look like it "disappeared".

Energy can't be created nor destroyed so it definitely can't just disappear though it can be converted or transformed.

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:

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Answer:

The force of car 3 on car 2 ≈ 1810.82 N

Explanation:

The equation for the change in momentum of the two cars are;

Conservation of linear momentum

150( 2.2 - v) = 265(1.5-v)

150 × 2.2 - 265×1.5 = (150+265)v

150 × 2.2 - 265×1.5 = -67.5 = 415×v

∴ v = -67.5/415 = -0.1627 m/s West = 0.1627 m/s East

The impulse of the net force is the amount of momentum change experienced given by the equation;

Impulse force = \(m \times v_f\) - \(m \times v_0\)

Where;

\(v_f\) = The final velocity

\(v_0\) = The initial velocity

For the the 265 kg mass, we have;

\(v_f\) = 0.1627 m/s

\(v_0\) = 1.5 m/s

Which gives the impulse a s F×Δt =  265×0.1627 - 265×1.5 = -354.38 kg·m/s

The change in kinetic energy of the collision = 1/2×265×(0.1627^2 - 1.5^2) =-294.62 J

Whereby the distance moved in one second is 0.1627 m, we have;

Work done = Force × Distance = Force × 0.1627 = 294.62

Force = 294.62/0.1627 = 1810.82 N.

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.
