gravity?

Explanation:

i dont have a lot of context but this is what i thought of so...

Stars and planets form when dust and gas from space is pulled together by gravitation.

In mechanics, gravity, often known as gravitation, is the force of attraction that acts on all matter. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

Hence, the stars and planets form when dust and gas from space is pulled together by gravitation.

The resistance increases as the diameter of the wire increases. Also, the voltage is constant and the current increases.

The term resistance refers to the opposition offered to the flow of current by circuit elements. The resistance of a wire depends on its;

Now, the diameter of the wire determines its cross sectional area. The resistance increases as the diameter of the wire increases. The voltage is constant  and the current increases since voltage and current are directly proportional to each other. The correct answer therefore is option A.

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question

m = 80 g = 0.08 kg

v = 15 m/s

We have

[tex]KE = \frac{1}{2} \times 0.08 \times {15}^{2} \\ = 0.04 \times 225[/tex]

Unless interrupted, it could refer to Newton's The rule of it in motion remains in motion. Consequently, if they throw it one way because there are no molecules to interrupt your course, you can continue to go the other way.

When the personal opinions, Ideas, or judgments of the researchers influence their research, then the experimental investigation and observation are considered biased, therefore the correct answer is option D.

Scientific claims are statements made in science based on an experiment.

These Scientific claims are backed by experimental data and their true results obtained from scientific investigation and experimentation.

The right response is option D because experimental study and observation are deemed biased when the researchers' own ideas, beliefs, or judgments affect their findings.

Answer:

The acceleration is a = 2.75 [m/s^2]

Explanation:

In order to solve this problem we must use kinematics equations.

[tex]v_{f} = v_{i} + a*t\\[/tex]

where:

Vf = final velocity = 13 [m/s]

Vi = initial velocity = 2 [m/s]

a = acceleration [m/s^2]

t = time = 4 [s]

Now replacing:

13 = 2 + (4*a)

(13 - 2) = 4*a

a = 2.75 [m/s^2]

Explanation:

Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.

Fermentation of glucose by yeast produces ethyl alcohol and carbon dioxide. (option a)

Fermentation is a metabolic process that occurs in yeast and some other microorganisms when they lack oxygen. During this process, glucose, a simple sugar, is broken down into simpler compounds. The main goal of fermentation is to produce energy for the cell without the need for oxygen.

Yeast, a type of fungus, carries out alcoholic fermentation. In this process, yeast breaks down glucose into two primary products: ethyl alcohol (also known as ethanol) and carbon dioxide. The equation representing this fermentation process is as follows:

Glucose → Ethyl Alcohol + Carbon Dioxide + Energy

The carbon dioxide produced during fermentation is responsible for the formation of bubbles in dough, which causes bread to rise. It is also the reason behind the effervescence in alcoholic beverages like beer and champagne.

So, the correct option is (a).

Answer:

D. Velocity

Explanation:

Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Although a vector has magnitude and direction, it does not have position.

Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity – it is the speed of an object in a particular direction.

Complete question is;

A ski jumper travels down a slope and leaves the ski track moving in the horizontal direction with a speed of 24 m/s. The landing incline below her falls off with a slope of θ = 59◦ . The acceleration of gravity is 9.8 m/s².

What is the magnitude of the relative angle φ with which the ski jumper hits the slope? Answer in units of ◦

Answer:

14.08°

Explanation:

The time covered will be given by the formula;

t = (2V_x•tan θ)/g

t = (2 × 24 × tan 59)/9.8

t = 8.152 s

Now, the slope of the flight path at the point of impact will be given by the formula;

tan α = V_y/V_x

We are given V_x = 24 m/s

V_y will be gotten from the formula;

v = gt

Thus;

V_y = gt

V_y = 9.8 × (8.152) = 78.89 m/s

Thus;

tan α = 78.89/24

tan α = 3.2871

α = tan^(-1) 3.2871

α = 73.08°

Thus ;

Relative angle φ = α - θ = 73.08 - 59 = 14.08°
