Answer: 10 m/2^2
F=ma
Explanation:
Force = 1000N
1 N is 1 (kg*m/s^2)
Mass = 100kg
F=ma
a = F/m
a = (1000kg*m/s^20/(100kg)
a = 10 m/s^2
Zeb was lifting a box onto a moving truck. He lifted with a net force of 2000N and the box had a mass of 100 kg. What was the resulting acceleration?
Answer:
20 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{2000}{100} = 20 \\ [/tex]
We have the final answer as
20 m/s²Hope this helps you

which type of energy is stored in chemical compounds and released in chemical reactions?
Answer:
potential
Explanation:
In the absence of friction, explain why the horizontal component of a projectile’s velocity is a constant.
Answer:
This downward force and acceleration results in a downward displacement from the position that the object would be if there were no gravity. The force of gravity does not affect the horizontal component of motion; a projectile maintains a constant horizontal velocity since there are no horizontal forces acting upon it

How is temperature related to the physical change of a substance
Answer:
Temperature is a measure of the kinetic energy of particles in a substance. As temperature increases, the atoms or molecules in a substance gain energy. As temperature decreases, the particles lose energy. A change in the energy of particles causes a change in their arrangement. A change in the arrangement of particles can lead to a physical change.

A person pushes a 11.5KG lawn mower with an applied force of 70.0N along the 45.0-degree-handle. if the lawn mower moves at a constant velocity
Determine the net force on the mower:
Fnet=__N
Determine the horizontal component of applied force on the mower:
Fx=__N (round to 3 digits)
Determine the horizontal frictional force acting on the mower
Ff=__N (Round to 3 digits)
Calculate the applied force the person must exert on the mower for it to accelerate at a rate of 1.00m/s^2
F=__N (round to 3 digits)
Force is a vector quantity hence it can be resolved into a vertical and a horizontal components.
1) The horizontal component of the applied force is given by;
Fnet = F cos θ
Fnet = 70.0N × cos (45.0)
Fnet = 49.5 N
2) The horizontal component of the frictional force is;
F = -Ff + mgsinθ
F = applied force
Ff =mgsinθ - F
Ff = (11 × 10 × sin 45) - 49.5
Ff = 28.3 N
Horizontal component of Ff
28.3 N cos 45 = 19.9 N
3) The applied force is given by;
F = 11 Kg × 1.00m/s^2 = 11.0 N

A plant uses carbon dioxide and water to form food and oxygen. Why is this a chemical change?
Answer:
because when the plant inhales c02 it exhales oxgen
Explanation:
Answer:
The properties of carbon dioxide and oxygen are different.
Explanation:
A chemical change is defined as something that changes the substance of something (such as the creation of water from hydrogen and water), and can be figured out if chemical or physical based on different changes and properties. Your answer will be The properties of carbon dioxide and oxygen are different because these are two different elements (compounds in case of CO2) that combine to form a different substance, thus changing the identity of the substance.
Photosynthesis is a chemical reaction that occurs in plants by using radiant energy from sunlight. In this chemical reaction, carbon dioxide from the atmosphere and water from the soil are combined to produce sugar (glucose) that contains stored chemical energy.
A projectile is shot on level ground with a
horizontal velocity of 17 m/s and a vertical
velocity of 34 m/s.
-Find the time the projectile is in the air.
The acceleration due to gravity is 9.8 m/s2.
Answer in units of s.
-Find range R.
Answer in units of m.
Answer:
time rising = 34 / 9.8 = 3.47 sec
total time in air = 2 * 3.47 sec = 6.94 sec
(time rising must equal time falling)
R = 17 m/s * 6.94 s = 118 m
Can also use range formula
R = v^2 sin (2 theta) / g
tan theta = 34 / 17 = 2
theta = 63.4 deg
2 theta = 126.9 deg
sin 126.9 = .8
v^2 = 17^2 + 34^2 = 1445 m^2/s^2
R = 1445 * .8 / 9.8 = 118 m agreeing with answer found above
Help if you understood pleas and rhanks
Answer:
the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s
Explanation:
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.
To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).
Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.
Now, let's find the change in velocity between 8 seconds and 10 seconds:
Change in velocity = Final velocity - Initial velocity
Change in velocity = 2 m/s - 6 m/s
Change in velocity = -4 m/s
Next, find the time interval between 8 seconds and 10 seconds:
Time interval = Final time - Initial time
Time interval = 10 s - 8 s
Time interval = 2 seconds
Now, calculate the acceleration:
Acceleration = Change in velocity / Time interval
Acceleration = (-4 m/s) / (2 s)
Acceleration = -2 m/s²
The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

what is the angular speed of the tip of the minute hand on a clock, in rad/s?
Answer:
0.10472 radians/minute
Explanation:
It completes a full rotation around that circular clock in 60 minutes. So the angular speed of the minute hand is 2 * pi / 60 = pi / 30 = 0.10472- radians/minute .
The angular speed is the ratio of angular displacement to time. Then the angular speed is π/1800 radians per second.
What is angular speed?The rate of change of angular displacement is called angular speed.
We know that the angular speed formula
[tex]\rm Angular \ speed = \dfrac{Angular \ displacement }{time}[/tex]
The angular speed of the tip of the minute hand on a clock, in rad/s, will be given as
We know that in one hour it rotates 360 degrees or 2π. And in one hour we have 3600 seconds. Then the angular speed will be
[tex]\rm Angular \ speed = \dfrac{2\pi}{3600}\\\\\\Angular \ speed = \dfrac{\pi}{1800}[/tex]

Explain this phase diagram by relating what you know about temperature, states of matter and
pressure.
Answer:
See explanation
Explanation:
The vertical axis corresponds to the pressure of a substance, while the horizontal axis corresponds to the temperature. The solid is the substance which contains particles of strong intermolecular force and compaction, typically ionic at a certain temperature, the liquid is the substance which contains relatively compact molecules, however lacks a particular arrangement. The gaseous substance is caused by particles with weak intermolecular forces, causing particle movement and collision with no arrangement whatsoever. The triple point as shown in the diagram, is the phrase on a diagram where each substance: solid, liquid and gas coexist. The critical point is the phase at which the/a substance is indistinguishable between liquid and gaseous states. A substance or elements state is highly dependent on its environment and it’s temperature, of which ultimately affects its kinetic energy within its particles. This is what the graph portrays and represents.
