35 degrees Fahrenheit is 1.66667 degrees in Celcius. Written in Kelvin, 35 degrees Fahrenheit would be 274.817 K.

Celcius:

(35°F − 32) × 5/9 = 1.667°C

Kelvin:

(35.001°F − 32) × 5/9 + 273.15 = 274.817K

F to C formula:

(32°F − 32) × 5/9 = 0°C

F to K formula:

(°F − 32) × 5/9 + 273.15 = K

Answer:

hold the plant in the ground

keep the plant upright

absorb water from the soil

take in nutrients from the soil

transport water and nutrients to the plant

provide a place for food storage

Explanation:

The plants are very complex organisms and can be classified into various types based on certain characteristics. The roots are very important structures which provide a lot of functions.

The roots are the important underground part of all the vascular plants. This part of the plant is generally responsible for anchoring it down into the ground and absorbing all the essential minerals, nutrients, and water from the soil.

The root of the plant also help us to store the food. The roots are not the reproductive part of the plants, they are called the vegetative parts. In certain plants, the roots are the means of reproduction. This type of reproduction is called the vegetative reproduction.

The roots also check the soil erosion, provide sustenance and also habitat for various organisms. The root absorb water and minerals from the soil and help in the process of photosynthesis.

Answer:

because the friction/movement of the bikes wheels, generates electricity and energy that the light can use to generate electricity and it also does not have a battery on it and relies on the wheels to generate the electricity for the light to work.

Explanation:

When a butane lighter is lit, chemical energy transforms into heat energy.

Energy cannot be created or destroyed, says the law of conservation of energy. However, it has the ability to change its form. The total energy of an isolated system is constant when all sources of energy are taken into account.

The chemical energy is the bonds of chemical molecules contain energy. Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.

In butane energy is stored as a chemical energy as  bonds of chemical molecules and when it is lit, the chemical energy of the butane transforms into heat energy.

Homogenous Mixture

Explanation:

When the scientist heated sugar and water, until the sugar was completely dissolved, then the mixture is a homogeneous mixture, also known as a solution.

A mixture is a combination of two or more substances that are physically combined in a way that each retains its own identity and properties. The substances that make up a mixture are called components or constituents, and they can be either elements or compounds.

Mixtures can be classified as homogeneous or heterogeneous, depending on whether the components are uniformly distributed or not.

In a homogeneous mixture, the components are evenly distributed throughout the mixture, resulting in a uniform composition and appearance.

In a heterogeneous mixture, the components are not uniformly distributed, and the mixture may contain visible boundaries or phase separations.

Mixtures can be created by mixing substances together using physical methods, such as stirring, shaking, or heating. Unlike chemical reactions, which involve the formation of new substances with different properties, mixtures can be separated back into their individual components by physical means, such as filtration, evaporation, or distillation.

Here in the question,

The mixture created from the water and sugar solution is a homogeneous mixture, also known as a solution. In a homogeneous mixture, the components are uniformly distributed throughout the mixture, resulting in a uniform composition and appearance. In this case, the sugar molecules are evenly dispersed throughout the water molecules, creating a clear and transparent solution.

Therefore, The mixture created from the water and sugar solution is a homogeneous mixture,

Answer:

2 hour

Explanation:

car will cover 80km in 1 hr

odometer's reading increases 160 km

so 80km = 1hr

then, 160km =1/80×160

=2 hr

Answer:

120 mins

Explanation:

delta X = 860 - 700      V = 80km/hour

t= delta x/ v= (860-700)/80= 2hours

2 hours = 120 mins

Answer:

L = V × I × t

P = V × I then

P = L/t

P = 64000J/200s= 320W

Answer: 136 Newtons (136N)

Explanation:

Newton's Law of Gravitation states that the gravitational force is proportional to the masses of the two objects, and their separation distance between them. The proportionality constant is called Newtons constant denoted as capital 'G':

[tex]F=GMm/r^2[/tex]

Now, due to Newton's 2nd Law of motion, we know that a net force acting on an object causes an acceleration. We can also say that the force is:

[tex]F=ma[/tex]

Setting both of these equations equal to each other, we get:

[tex]ma=GMm/r^2[/tex]

The smaller 'm' will cancel giving that the acceleration is:

[tex]a=GM/r^2[/tex]

This is the equation which gives the gravitational field created from a source mass 'M'. To find the weight, find the product between the test mass and the gravitational field created by the source mass:

[tex]Weight=mass*acceleration[/tex]

[tex]W=ma[/tex]

[tex]W=(85kg)(1.6m/s^2)[/tex]

[tex]W=136N[/tex]

The units are Newtons due to weight being a force.

a house or a land is used to secure a mortgage loan

a house or a land is used to secure a mortgage loan. Hence option D is correct.

A loan is the lending of money by one or more persons, organisations, or other entities to other individuals, organisations, or other entities in finance. The recipient (i.e., the borrower) incurs a debt and is often required to pay interest on that loan until it is repaid, in addition to repaying the primary amount borrowed.

The paper demonstrating the loan (for example, a promissory note) will often indicate the principal amount borrowed, the interest rate charged by the lender, and the date of repayment. A loan is the temporary reallocation of the subject asset(s) between the lender and the borrower.

The interest serves as an inducement for the lender to make the loan.

Given is that a current is induced by moving a magnet in and out of a coil of wire.

As the magnet moves twice as fast, then the rate of change of magnetic flux will increase and hence the induced current will increase.

Therefore, we can conclude that the induced current will increase.

A 615 N student standing on a scale in an elevator notices that the scale reads 645 N. From this information, the student cannot tell that if the elevator is moving upward or downward. The correct answer is option C.

The reason for this is that the scale reading depends not only on the weight of the student but also on the acceleration of the elevator. If the elevator is accelerating upwards, the scale will read more than the actual weight of the student.

Similarly, if the elevator is accelerating downwards, the scale will read less than the actual weight of the student.

In this case, we know that the scale reads 645 N, which is 30 N more than the actual weight of the student (615 N).

However, we don't know whether the elevator is accelerating upwards or downwards. It could be accelerating upwards with an acceleration of 3 m/s^2 (in which case the apparent weight would be 645 N), or it could be accelerating downwards with an acceleration of 3 m/s^2 (in which case the apparent weight would be 585 N).

Therefore, based on the information given, we cannot determine whether the elevator is moving upwards or downwards. The correct option is c.
