A plane starts out at rest. 100 seconds later, its velocity is 300 m/s. What
vas its average acceleration during this time?
Answers
Answer:
3 m/s^2
Explanation:
avg. acceleration= (change velocity)/ time
[v(final)-v(initial)]/(t2-t1)
[(300 m/s)-(0 m/s)]/(100s-0)
(300 m/s)/(100s)
= 3 m/s^2

Answer:
Explanation:
the cells need oxygen for metabolism, which also creates carbon dioxide as a waste product. The red blood cells then pick up the carbon dioxide and transport it back to the lung. There we exhale it when we breathe out. Red blood cells can also pick up or release hydrogen and nitrogen.
The table shows experimental data of the magnitude of four forces exerted on a 2kg object as it slides across a horizontal surface. Which of the following could represent the magnitude of the net force that is exerted on the object? Select two answers.
Answers
Answer:
6N and 10N
Explanation:
The forces acting along the horizontal axis arw the horizontal force applied and the frictional force.
Frictional force is a force that opposes the horizontal force (moving force)
First we need to get the sum of force along the horizontal as shown
\sum Fx = Horizontal force - frictional force
\sum Fx = 8N - 2N
\sum Fx = 6N
Hence one of the magnitude of the net force exerted on the object is 6N
For the forces along the vertical component;
The forces are the weight, force of gravity(acting downward) and the normal force acting upward
Given
Weight = mass × acceleration die to gravity
Weight = 2×10 = 20N
Normal force = 10N
\sum Fy = (weight)-normal force
\sum Fy = (20)-10
\sum Fy = 20-10 = 10N
Hence the other net force acting on the object is 10N
The required options are 6N and 10N

Which phase in the cell cycle consists of the cell readying itself for its division?
A.
Prophase
B.
Interphase
C.
Anaphase
D.
Metaphase
Answers
Answer:
A
Explanation:
The phase of cell cycle consists of the cell readying itself for its division is called prophase of the cycle. It is the first phase in mitosis at which a cell duplicate into two daughter cells.
What is cell cycle?Cell cycle is a biological process by which a cell divide into two genetically identical daughters cells. Prophase is the initial stage of cell division in both mitosis and meiosis. When the cell reaches prophase, DNA replication has already started after interphase.
The chromatin reticulum condenses and the nucleolus vanishes during prophase, which are the key events. Other phases are interphase, anaphase etc. and the last stage is called the telophase.
Cell cycle is a very important biological process by which organisms are producing their offspring. This process differ in each level of organism where for all the starting phase is called prophase.

The addition of any numbers of vector provide the magnitude as well as the direction of the resultant vector, hence the mentioned first option is not true.
The addition of vector required to connect the head of the one vector with the tail of the other vector and any vector can be moved in the plane parallet to the previous location, so, the mentioned second and third options are true.

In the complete description of a force vector, type is usually not necessary. Thus, the correct option is C.
What is Force vector?A force vector is a representation which has both the magnitude and direction of the force. Such a vector is typically represented through an arrow in the direction of the force applied and with a length which is proportional to the magnitude of the force.
If a force is applied on an object, this causes movement of the object in a given direction and the wind applies a force on it at an angle, and the new motion will be as that of a force which was applied in that direction.

a stone thrown horizontally from the top of a vertical wall with a velocity of 15m/s,hits the horizontal ground at a point 45m from the base of the wall. calculate the height of the wall. g =10m/s
Answers
Answer:
The height of the wall is 45 m
Explanation:
Horizontal Motion
When an object is thrown horizontally with an initial speed v from a height h, the maximum horizontal distance traveled by the object, also called the range can be calculated as follows:
[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]
If we know the range and want to calculate the height it was thrown from, we solve the equation for h:
[tex]\displaystyle h=\frac{d^2g}{2v^2}[/tex]
We'll use the approximate value of g=10\ m/s^2.
The stone was thrown from the top of a wall with a speed of v=15 m/s and it hits the ground d=45 m away from the base of the wall. Calculating:
[tex]\displaystyle h=\frac{45^2\cdot 10}{2\cdot 15^2}[/tex]
[tex]\displaystyle h=\frac{2025\cdot 10}{2\cdot 225}[/tex]
[tex]\displaystyle h=\frac{20250}{450}[/tex]
h = 45 m
The height of the wall is 45 m

1. How is the attractive electrostatic force between a proton and an electron indicated in Coulomb's law?
the sum of the charges indicates a positive force
the product of the charges indicates a positive force
the product of the charges indicates a negative force
the sum of the charges indicates a negative force
2. One particle has a negative charge, while another particle is neutral. Which statement describes the electrostatic force between these two particles?
There would be no electrostatic force because the sum of the two charges is 0.
The electrostatic force is attractive due to the particle with negative charge.
There would be no electrostatic force because the product of the two charges is 0.
The electrostatic force is repulsive due to the particle with negative charge.
3. How would the electrostatic force change if Coulomb's law included a negative sign?
Like charges would repel, and opposite charges would attract.
It would not make a difference in the electrostatic force.

Answers
Answer:
The product of the charges indicates a negative force
There would be no electrostatic force because the product of the two charges wld be zero
Like chargers wld attract, and opposite charges wld repel
Approximately 1.45 V/m directed away from the positive charge
Explanation:
According to Coulomb's law the electrostatic force is directly proportional to the product of the charges and inversely proportional to the distance separating them.
According to Coulomb's law;
F =[tex]Kq1q2/r^2\\[/tex]
Where;
K = constant of Coulomb's law
q1 and q2 are the respective magnitudes of the charges
r = distance separating the charges
Hence,according to Coulomb's law, the product of the charges indicates a negative force.
According to Coulomb's law, for a negative charge, and a neutral particle, there would be no electrostatic force because the product of the two charges is 0. If Coulomb's law included a negative sign then Like charges would attract, and opposite charges would repel.
The electric field is given by the formula;
[tex]E = kq/r^2\\k= 9 * 10^9 Nm^2C-2\\q =1 * 10^-9 C\\r = 2.5 m\\E = 9 * 10^9 Nm^2C-2 * 1 * 10^-9 C/( 2.5 m)^2\\E = 1.45 V/m[/tex]
The direction of the electric field is 1.45 V/m directed away from the positive charge.

15 percent input work is lost due to friction,then what is the efficiency of machine?
Answers
Answer:
{ (x/y )*100 } - 0.15 y
Explanation:
The efficiency of a machine is the percent of output work divided by input work minus work lost from friction and heat.
Assume work output = x
Assume work input percent as =y
Work lost through friction is given as : 15% input work = 0.15 y
Then efficiency of the machine will be :{ (x/y )*100 }- 0.15 y
Use real values for x and y to find the correct efficiency of the machine.
