Answer:
Acceleration = 6m/s²
Explanation:
Given the following data;
Initial velocity = 35m/s
Final velocity = 65m/s
Time = 5 seconds
To find the acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.Substituting into the equation, we have
[tex]a = \frac{65 - 35}{5}[/tex]
[tex]a = \frac{30}{5}[/tex]
Acceleration = 6m/s²
Review the following situations and determine whether each is an elastic collision or an inelastic collision. Choose the situations that are elastic collisions. Select all that apply.
A. Momentum is conserved; kinetic energy is not.
B. A moving hockey puck strikes one at rest; the objects exchange velocity.
C. Momentum and kinetic energy are conserved.
D. A collision between a volleyball and a basketball occurs; there is no deformation.

Answer:
Your answer would be D.
Please help !! I have no clue how to do this
Answer:
THIS IS SUPER EASY!!!!!!
BOLD = ANSWER
Explanation:
REMEMBER: force = mass x acceleration
4. 6.0kg x 4.0m/s2 = 24N
5. 7.5kg x 8.3m/s2 = 62.25N
6. 2,000kg x 8.3m/s2 = 16,000N
REMEMBER: mass = force / acceleration
7. 6.0N / 3.0m/s2 = 2kg
8. 6.0N / 12.0m/s2 = 0.5kg
9. 20.0N / 5.0m/s2 = 4kg
10. 20.0N / 2.0m/s2 = 10kg
11. 4.0N / 7.3m/s2 = 0.55kg
12. 4.6N / 16.3 m/s2 = 0.28kg
I hope this helps u! :D
According to Mendel's law of segregation, what takes place during meiosis?A.Pairs of alleles cross over on chromosomes, exchanging one for anotherb.Pairs of alleles separate in meiosis, and each gamete receives one allele of a pairc.Part of an allele is separated, or broken off, from its chromosomed.One chromosome is suppressed, and the other chromosome of the pair determines the traits of the offspring
Answer:
b. Pairs of alleles separate in meiosis, and each gamete receives one allele of a pair.
Explanation:
Gregor Mendel, who is referred to as the FATHER OF GENETICS because of his contribution to the principles of inheritance, proposed in one of his laws called LAW OF SEGREGATION that the alleles of a gene will separate into gametes in such a way that only one of the two alleles that make up a gene will be in each gamete.
This division/separation of alleles during gamete formation is called MEIOSIS. Note that, allele is one member of a gene. Hence, according to Mendel, in meiosis, pairs of alleles separate and each gamete receives one allele of a pair.
Attraction and repulsion are both forces that act over a distance without objects having to touch. Choose the statement below that best describes what happens when objects attract or repel without any outside force to interfere in their motion.
a
When objects attract or repel the motion depends the type of attracting or repelling that is happening.
b
When objects attract they pull each other together and when they repel the push each other apart.
c
When objects attract they push each other apart and when they repel they pull each other together.
d
When objects either attract or repel it's mostly the same thing.
answer:
b. when objects attract they pull each other together and when they repel the push each other apart.
explanation:
repel means to push each other apart (south vs south pole)attract means to pull each other (north vs south pole)like poles repel, while opposite poles attractWhat happens to the molecules when the solid changes phase?
they begin to move quickly and can break away from other molecules
Answer:
When solid changes atoms/molecules begin to speed up and move around. Compared to when they are in the solid phase, where they barely move and are slow and are compacted.

Norma drives her car for 150 min at 40 km/h, then rests for 75 min, and then drives for 3.15 h at 60 km/h. What was Norma’s average speed?
Answer:
Norma’s average speed is 41.9 km/h.
Explanation:
The average speed is given by:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} [/tex]
Where:
[tex]d_{T}[/tex]: is the total distance
[tex]t_{T}[/tex]: is the total time
We can find the total distance as follows:
[tex] d_{T} = v_{1}*t_{1} + v_{2}*t_{2} = 40 \frac{km}{h}*150 min*\frac{1 h}{60 min} + 60 \frac{km}{h}*3.15 h = 289 km [/tex]
Now, the total time is:
[tex] t_{T} = t_{1} + t_{2} + t_{3} = 150 min*\frac{1 h}{60 min} + 75 min\frac{1 h}{60 min} + 3.15 h = 6.9 h [/tex]
Hence, the average speed is:
[tex] \overline{v} = \frac{d_{T}}{t_{T}} = \frac{289 km}{6.9 h} = 41.9 km/h [/tex]
Therefore, Norma’s average speed is 41.9 km/h.
