Michelle and George are studying the forces and motion of a 0.8-kg low friction cart on a horizontal table. They use a spring sc

ale to exert different amounts of horizontal pulling force on the cart and measure the acceleration of the cart for each pulling force. The measurements of each set of pulling force and acceleration are displayed in the table below. If friction is much weaker than the pulling force, which of the following is the best fit for the missing pulling force in the table?

Table 1: The horizontal pulling forces (F) and resulting acceleration (a) for the cart.



The cart experiences no motion when there is 0.1 N of horizontal force, so F=0 in this case. When one uses Newton's Second Law to find the acceleration caused by each force, it becomes clear that every row in the chart represents a horizontal force of approximately F=20 N. The best fit for the missing value is F=-30N.

What do the letters inside the grid of a punnett square represent?
Aneli [31]

Answer:

The correct answer is - Genotype of the offspring

Explanation:

Punnet square is a diagram which is used to predict and show the genotype of offspring that is produced by a cross between male and female gametes. This approach was given by Reginald C. Punnett.

Each grid have a genotype that can determine the phenotype of offspring. The letters used in to fill these grids can be made up of uppercase letters, lower case letters or both. The allele shown in upper case letters shows that the allele is dominant and the allele which is in lowercase letter is a recessive allele.

Therefore the letters inside the grid of a punnet square represents the genotype of the offsprings.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle
kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°

What type of organism is always found on the first step
Fed [463]
No organism is always the first step, except in a wide sense, plants. In the water, plankton is found in first but whereas on land, plants or seeds are eaten first.

Hope it helped!! :)

What foods have the least impact on slowing the body's absorption rate of alcohol.
daser333 [38]

The right answer is foods that are high in fiber.

Alcohol passes into the esophagus and ends up in the stomach. 20% of this alcohol crosses the wall of the stomach to end up in the blood. Then the alcohol left in the stomach passes into the small intestine, which assimilates it quickly. The liver partly breaks down the alcohol that has passed into the bloodstream.

Alcohol reaches the brain, after about 10 minutes, through the blood. It is then that this part of the body and the nervous system undergo the effects (narcotics). The assimilation of alcohol lasts longer if The person is not fasting at that time (it will be necessary to avoid carbohydrate-based foods and to favor fatty and protein-rich foods to attenuate the absorption).
