During a baseball game, a batter hits a high
pop-up.
If the ball remains in the air for 5.93 s, how
high above the point where it hits the bat
does it rise? Assume when it hits the ground
it hits at exactly the level of the bat. The
acceleration of gravity is 9.8 m/s
2. Answer in units of m.
Answer: 43.01 m
Explanation:
Given that :
Time ball uses in the air = 5.93, time it takes to reach maximum height and return = time of flight(T) = 5.93 s
TIME of flight (T) = 2 * time taken(t)
Where g = a = acceleration due to gravity = 9.8m/s²
S = 0.5at²
S = maximum height
Tjme taken (t) = time of flight / 2 = 5.93/2 = 2.965 s
Hence,
S = 0.5at²
S = 2 × 0.5 × 9.8 × 2.965²
S = 43.0770025
S = 43.01 m

What is ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7).
A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.
Let, sea level is x meter below the submarine in the model.
According to the question:
x: 1000 =1:500
x/1000 = 1/500
x = 1000/500
x = 2
Hence, the sea level is 2 meter below the submarine in the model.

A student leaves their history classroom and walks 20 meters north to a drinking fountain. Then the student turns and walks 50 meters south to their art classroom. What is the magnitude of the total distance traveled by the student?
a. 20 m
b. 30 m
c. 50 m
d. 70 m
Answer:
D
Explanation: Given that a student leaves their history classroom and walks 20 meters north to a drinking fountain. Then the student turns and walks 50 meters south to their art classroom.
The distance is a scalar quantity.
The distance = 50 + 20
distance = 70 metres
Therefore, the magnitude of the total distance traveled by the student is 70 metres. Which is option D

What is DNA?A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction.
Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).
Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

3. A man heads up a trail going north to see a lake. The trail is 5 miles long and it takes him
2 hours to get there. What was his velocity?
Answer:
v = 2.5 mi/h
Explanation:
The velocity of an object is defined as the time rate of change of its position. In other words the velocity of an object is just a ration of displacement covered by the object to the time taken by the object, to cover that distance. So, in this case we will use the same formula or equation to calculate the velocity of the man. The formula is as follows:
v = s/t
where,
v = velocity of the man = ?
s = distance of the trail = 5 miles
t = time required to complete the trail = 2 h
Therefore,
v = 5 miles/ 2 h
v = 2.5 mi/h

A circular pizza into 3 equal parts, one piece of pizza is taken out. Estimate the degree measure of the single piece of pizza and convert the measure into radians. What is the radian measure of the angle of the remaining part of pizza?
Answer:
A circular pizza has a angle of 360 degrees. When you cut it into 3 equal pieces you divide 360 by 3,you get 120 degrees. And following the conversion of 120 degree into radian you get 2pie/3 radians.
Answer:
Explanation:
The total degree of the circle = 360°
It is divided into 3 equal parts, so each part becomes 360 / 3 = 120°
conversion of 120 degree into radian you get 2pie/3 radians.

You are going for a drive, but a detour takes you out of the way of your destination. You
drive north for 10 miles, turn right and drive east for 5 miles, turn to the north and drive for 3
miles, drive west for 10 miles, and arrive at your destination.
a) How far from where you started did you end up?
b) If you wanted to travel directly to your destination without following the streets (“as the
crow flies”), what angle would you take? What direction would a compass read?
c) Now try adding the vectors in a different order. For example, start with the 5 miles east,
then 3 miles north, etc., as long as you add all four vectors. Compare the result to the sum
in part a). Draw the vectors in the order you used.
Answer:
(a). The distance between started point and end point is 13.92 miles.
(b), The direction is 68.9° north - west.
Explanation:
Given that,
You drive north for 10 miles, turn right and drive east for 5 miles, turn to the north and drive for 3 miles, drive west for 10 miles, and arrive at your destination.
According to diagram
(a).We need to calculate the distance
Using pythagorean theorem
[tex]EO=\sqrt{(ED)^2+(DO)^2}[/tex]
Put the value into the formula
[tex]EO=\sqrt{5^2+(13)^2}[/tex]
[tex]EO=13.92\ miles[/tex]
(b). We need to calculate the direction
Using formula of direction
[tex]\theta=\tan^{-1}(\dfrac{OD}{DE})[/tex]
Put the value into the formula
[tex]\theta=\tan^{-1}(\dfrac{13}{5})[/tex]
[tex]\theta=68.9^{\circ}[/tex]
The direction is 68.9° north - west.
(c). We need to draw a vector diagram
According to vector diagram,
The distance between started point and end point will be same.
Hence, (a). The distance between started point and end point is 13.92 miles.
(b), The direction is 68.9° north - west.

An observer sitting at a bus stop sees the bus drive by at 30 m/s to the east. He also sees a
passenger on the bus walking to the back at 2 m/s. What is the passenger's velocity relative
to the bus?
Answer:
32 m/s
Explanation:
The speed of a bus is 30 m/s due East wrt the passenger
He also sees a passenger on the bus walking to the back at 2 m/s.
We need to find the passenger's velocity relative to the bus. As the observer sees that the bus and the passenger are moving in opposite direction. Let v is the relative velocity. So,
v = 30 m/s + 2 m/s
v = 32 m/s
Hence, the passenger's velocity relative to the bus is 32 m/s.

If you move 3 meters East and move 4 meters north what is the distance and what is the displacement?
Answer:
Explanation:
The distance will be the total distannce covered during the journey.
If you move 3 meters East and move 4 meters north, then the distance will be calculated as;
Distance = distnace through East+distance through north
Distance = 3m + 4m
Distance = 7m
Displacement is the distance covered in a specified direction. It is the shortest distance covered by me. This can be gotten using the Pythagoras theorem.
d² = 3²+4²
d² = 9+16
d² = 25
d = √25
d = 5m
Hence the displacement of the object is 5metres

A car travels 90 meters due North in 15 seconds. The car turns around and travels 40 meters due south in 5 seconds. What is the magnitude of the average velocity of the car during this 20-second interval?
Answer:
5m/s
Explanation:
If you do 90-40 (the two distances the problem gave) which will give you 50 meters, and then 15-5 (the two times given) which will give you 10. All you do after that is divide your new found distance with your new time 50/10 and boom chicken soup you got your final answer of 5 m/s :)
We have that The cars displacement is
d=50m
The magnitude of the average velocity is
Avg V=2.5m/s
From the question we are told
A car travels 90 meters due North in 15 seconds. The car turns around and travels 40 meters due south in 5 seconds. What is the magnitude of the average velocity of the car during this 20-second interval
Generally the equation for the Total displacement is mathematically given as
d=initial displacement -final displacement
Therefore
d=90-40
d=50m
Generally the equation for the average velocity is mathematically given as
[tex]Avg V=\frac{m}{s}\\\\Avg V=\frac{50}{20}[/tex]
Avg V=2.5m/s
Therefore
The cars displacement is
d=50m
The magnitude of the average velocity
Avg V=2.5m/s
