An object is thrown downward from the top of a 175 meter building with an initial speed of 10m/s
Answer:
Explanation:
we can look for the final velocity of the object using the eqaution of motion as shown:
v² = u²+2gH
v is the final velocity
u is the initial velocity = 10m/s
g is the acceleration due to gravity = 9.81m/s²
H is the height of the object = 175m
Subxtitute the given parameters inti the formula and get v:
v² = 10²+2(9.81)(175)
v² = 100+3433.5
v² = 3533.5
v = √3533.5
v = 59.44m/s
Hence the final velocity of the object is 59.44m/s

3. What is the mass of a paratrooper who experiences an air resistance of 400 N and an acceleration of 4.5 m/s2
during a parachute jump.
Answer:
88.89kg
Explanation:
The formula for mass is m=F/a. If we plug in the values, we get m=400N/4.5m/s^2. The mass is 88.89kg. We know that the unit is in kg because one newton (N) is 1kg*m/s^2. The m/s^2 is cancelled out by the acceleration, and we are left with kg.

The image here shows four soccer balls at four different locations on an uneven soccer field very near sea level. Which soccer ball has the greatest amount of potential energy?
Ball B
Ball C
Ball A
Ball D
Answer:
The answer is B.
Explanation:
Because that's the one that's more-so higher up than the other soccer balls. This grants the ball to have higher potential energy than the rest.
Quote:
"Your body is as weak as your soul, so it is easy to separate the two."
- Akuma
The ball b would have the greatest amount of the potential energy as the mass of each ball is the same then the ball on the highest altitude would have the greatest amount of the potential energy contained with it.
What is mechanical energy?Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.
The mechanical energy = potential energy + kinetic energy
As given in the problem, the image here shows four soccer balls at four different locations on an uneven soccer field very near sea level.
The potential energy of the ball = mass×gravity×height
Since each ball's mass is the same, the ball at the highest altitude would have the most potential energy within it. As a result, ball b would have the greatest quantity of potential energy.
Thus,the correct answer is option A.

The mass of an unidentified rock is 15.5 grams. Students determine the volume of the rock by placing the rock in a cylinder with water. The students calculate the density of the rock. They determine the identity of the rock based on the density ranges in the table.
The students most likely have which type of rock?
Coal
Dolomite
Peridotite
Sandstone
Answer:
this density is in the range of Peridotite type rocks
Explanation:
In this graduated cylinder exercise we can directly read the volume of the rock
V = (35 - 30) cm³
V = 5 cm³
They also indicate the mass of the rock
m = 15.5 gr.
Density is defined as the ratio of mass to volume
ρ = 15.5 / 5
ρ= 3.1 gr /cm³
When checking the attached table this density is in the range of Peridotite type rocks
The type of rock the students mostly like have is Peridotite.
We'll begin by calculating the volume of the rock. This can be obtained as follow:
Volume of water = 30 mL
Volume of water + rock = 35 mL
Volume of rock =?Volume of rock = (Volume of water + rock) – (Volume of water)
Volume of rock = 35 – 30
Volume of rock = 5 mLFinally, we shall determine the type of rock the students have by calculating the density of the rock. This can be obtained as follow:Volume of rock = 5 mL = 5 cm³
Mass of rock = 15.5 g
Density of rock =?Density = mass / volume
Density of rock = 15.5 / 5
Density of rock = 3.1 g/cm³Comparing the density of the rock (i.e 3.1 g/cm³) with those given in table above, we can conclude that the rock is peridotiteLearn more: https://brainly.com/question/2040396

a car is initially moving at 10 m/s and accelerates at a constant rate of 2 m/s^2 for 4 seconds, in a straight line. How far did the car carvel during this time?
A car is initially moving at 10 m/s and accelerates at a constant rate of 2 m/s², then the car will travel 56 meters.
What is Acceleration?The rate of change in an object's velocity concerning time is known as acceleration in mechanics. The vector quantity of accelerations. The direction of the net force that is acting on an object determines its acceleration.
Since acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is a vector quantity as well. The definition of acceleration is the change in velocity vector over a time interval divided by the time interval.
There are several types of acceleration :
Uniform AccelerationNon-Uniform AccelerationAverage AccelerationAccording to the question, the given values are :
Initial Speed, u = 10 m/s
Acceleration, a = 2 m/s²
Time, t = 4 sec.
Use the Equation of motion to find the distance,
s = ut + 1/2 at²
s = 10(4) + 1/2 (2)(4)²
s = 40 + 16

Fermentation of glucose by yeast produces
A) ethyl alcohol and carbon dioxide.
B) lactic acid and carbon dioxide.
C) lactic acid and oxygen.
D) ethyl alcohol and oxygen.
Answer:
A
Explanation:
Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.
Fermentation of glucose by yeast produces ethyl alcohol and carbon dioxide. (option a)
Fermentation is a metabolic process that occurs in yeast and some other microorganisms when they lack oxygen. During this process, glucose, a simple sugar, is broken down into simpler compounds. The main goal of fermentation is to produce energy for the cell without the need for oxygen.
Yeast, a type of fungus, carries out alcoholic fermentation. In this process, yeast breaks down glucose into two primary products: ethyl alcohol (also known as ethanol) and carbon dioxide. The equation representing this fermentation process is as follows:
Glucose → Ethyl Alcohol + Carbon Dioxide + Energy
The carbon dioxide produced during fermentation is responsible for the formation of bubbles in dough, which causes bread to rise. It is also the reason behind the effervescence in alcoholic beverages like beer and champagne.
So, the correct option is (a).

A 4kg block and a 2kg block can move on horizontal frictionless surface. The blocks are accelerated by a +12-N force that pushes the large block against the smaller one.'
a) Determine the force that the 2kg block exerts on the 4kg block
b) Determine the force that the 4kg block exerts on the 2kg block.
Answer:
a) -4 N
b) +4 N
Explanation:
Draw a free body diagram for each block.
For the large block, there are 2 forces: 12 N pushing to the right, and F pushing to the left.
For the small block, there is 1 force, F pushing to the right.
There are also weight and normal forces in the vertical direction, but we can ignore those.
Sum of forces on the large block in the x direction:
∑F = ma
12 − F = 4a
Sum of forces on the small block in the x direction:
∑F = ma
F = 2a
2F = 4a
Substitute:
12 − F = 2F
12 = 3F
F = 4
The small block pushes on the large block 4 N to the left (-4 N).
The large block pushes on the small block 4 N to the right (+4 N).
