A 6,000 kg train car is moving to the right at 10 m/s and connects to a 4,000-kg train car that wasn't moving. What is the veloc
SIZIF [17.4K]

6 m/s

This type of collision is a <u>Inelastic collision </u>

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv  whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

In pigs, curly tails (T) are dominant over straight tails (t). If a pig is heterozygous for a curly tail, what is the pig's geno
n200080 [17]

Answer:

The pig's genotype is Tt

Explanation:

As mentioned in the question that curly hair allele T is dominant over straight tail allele t.

A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.

Hope it helps! :)
