If two objects are compared at a certain distance, according to Newton’s law of universal gravitation, what is true? Complete th
Xelga [282]

1. Both objects have mass and therefore have  a gravitational force.

2. Lower mass objects have  less gravitational force.

3. Higher mass objects have  stronger gravitational force.

Explanation:

To solve this problem, we need a recap of the newton's law of universal gravitation:

The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."

   F = \frac{G[tex]m_{1} m_{2}}{r^{2}}[/tex]

 G = universal gravitational constant

 m₁ = mass of object 1

 m₂ = mass of object 2

  r² = distances between the two masses

From this we can infer that, for gravitational force to exists, both objects must have mass.

Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

C) One plant with genotype YySs is crossed with another plant with the same genotype. Use the Punnett
Volgvan

Answer:

(See Attached Punnet Sq)

Explanation:

There are two genes here represented different alleles (Yy & Ss). According to Mendelian law, the principle of independent assortment applies to mean each allele has equal chances of ending up in a gamete. Therefore each gamete can have either allele of the two genes as shown in the punnet square. The combinations of the offspring are therefore numerous.
