a wagon has a mass of 100 kg an acceleration of 2m/s/s. What is the force on the wagon?
Answer:
200N
Explanation:
Given parameters:
Mass of wagon = 100kg
Acceleration = 2m/s²
Unknown:
Force on the wagon = ?
Solution:
From Newton's second law of motion:
Force = mass x acceleration
Now insert the parameters and solve;

Can there be displacement of an object in the absence of any force acting on it? Think, Discuss it with your friends and teacher?
Answer:
An object can have a displacement in the absence of any external force acting on it
Explanation:
When a object moves with a constant velocity (v), then it gets displaced in the direction of motion but the net external force experienced by the object is zero.
F external =ma
If object moves with constant velocity, acceleration is zero.
Since, a=0 ⟹F external =0
Using s=ut+ 1/2 at ^2
⟹ Displacement s=ut (∵a=0)
Hence, an object can have a displacement in the absence of any external force acting on it

A girl during a hike has a bottle of mineral water in her haversack. The bottle has 2 litres of water in it (2ltr. weigh 2kg). The water gets heated by the sun by 5 °C. How much heat has the water absorbed from the sun?
Answer:
Q = 41800[J]
Explanation:
These types of problems can be solved using the following heat transfer equation for quarps that increase or decrease their temperature as a function of mass.
[tex]Q=m*C_{p}*DT[/tex]
where:
Q = Heat absorbed [J]
m = mass = 2 [kg]
DT = temperature change = 5 [°C]
Cp = specific heat of the water = 4180 [J/kg*°C]
[tex]Q=2*4180*5\\Q=41800[J][/tex]

Do you believe that global warming is happening? Tell why or why not. If you believe global warming is happening, what can we do to slow it down?
Answer:
Yes I do believe global warming is happening, mainly because there is a plethora of data and research from scientists to support the claim. The effects of global warming around us are clearly observed as well, such as the rise in acidity in the oceans. Another example is in the Artic, where a natural occurence takes place. Ice freezes and cold salty water takes its place, and because of it's high density it sinks and sweeps across the ocean floor. That cold water is then replaced by warmer water, and this is called the global ocean conveyor belt. As seen through the example with the Artic, ocean temperature plays a key role in the conveyor belt. Climate change is fueled through human activities, which could harm the system. If one part of the conveyor belt were to break down, such as the one in the Artic, nutrients will not be distributed to start the food chain. Organisms such as phytoplankton need those nutrients to thrive. If phytoplankton are endangered, all life in the oceans is endangered. So as we can see, global warming is extremely harmful to the environment and it's effects are observed around us.
To slow global warming down we should consume less meat, and go to vegan or vegetarian diets. Your carbon footprint is halved by consuming less meat and eating a more vegan or vegetarian diet. Another thing is that we as a society should stop using so much plastic. It takes more than a century to degrade, most landfills are composed of it. Microplastics also get into our oceans, and our fish end up consuming them.

If the mass of a box is 200 Kg, with what net force would you use to make the box accelerate 2.4 m/s 2 ?
Answer:
The net force used on the box was 480 N
Explanation:
Mechanical Force
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = ma
Where a is the acceleration of the object.
The mass of a box is m=200 kg and it's accelerated at a=2.4\ m/s^2 by a net force whose magnitude is:
F = 200 * 2.4 N
F = 480 N
The net force used on the box was 480 N

Jada runs exactly 2 laps around a 400 meter track. What is the displacement?
a:
0
b:
400
c:
800
Answer:
Option B 400meters
Explanation:
What is displacement
Displacement is a vector whose length is the shortest distance from the initial to the final position of a point P undergoing
Given data
number of laps = 2
length of lap= 400meters
Since after every one lap she returns to her initial position ]
the displacement is 400meters
Which of the following has zeros that are not significant?
2.05 m/s
10.0 J
1.30 N
100 kg
Answer: Either 10.0 J or 1.30 N
Explanation:
10.0 J
if it was 10.01 it would be significant, but its 10.0 which makes it a whole number
1.30 N
All zero's preceding the first integers are never significant. For example: 0.0078 has two significant figures. All zero's after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures
Answer:
100 kg
Explanation:
With the absence of a decimal point, only the 1 would be significant.

What evidence do we have that Earth has a magnetic field surrounding the planet?
A compass works the way it does because Earth has a magnetic field that looks a lot like the one in a magnet.
What is magnetic field?The Earth's field is completely invisible, but it can be felt by a compass needle on the Earth's surface, and it reaches thousands of miles out into space.
Mathematically, the magnetic field is represented as a vector field. This vector field can be easily visualized as a collection of several vectors laid out in a grid. Each vector has a length based on the strength of the magnetic field and points in the same direction as a compass would.
This method is demonstrated by placing a grid of numerous small compasses in a magnetic field. The only distinction is that a compass does not reveal the strength of a field in this instance.
Therefore, A compass works the way it does because Earth has a magnetic field that looks a lot like the one in a magnet.

A man standing on top of a 30 m tall building throws a brick downwards with a velocity of 12 m/s. Determine the speed of the brick just before it hits the ground.
Answer:
27.1m/s
Explanation:
Given parameters:
Height of the building = 30m
Initial velocity = 12m/s
Unknown:
Final velocity = ?
Solution:
We apply one of the kinematics equation to solve this problem:
v² = u² + 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
v² = 12² + (2 x 9.8 x 30)
v = 27.1m/s
Which graph accurately shows the relationship between kinetic energy and speed as speed increases?
Answer:
B
Explanation:
kinetic energy (KE) is the energy possessed by moving bodies. It can be expressed as:
KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]
Where: m is the mass of the object, and v its speed.
For example, a stone of mass 2kg was thrown and moves with a speed of 3 m/s. Determine the kinetic energy of the stone.
Thus,
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]3^{2}[/tex]
= 9
KE = 9.0 Joules
Assume that the speed of the stone was 4 m/s, then its KE would be:
KE = [tex]\frac{1}{2}[/tex] x 2 x [tex]4^{2}[/tex]
= 16
KE = 16.0 Joules
Therefore, it can be observed that as speed increases, the kinetic energy increases. Thus option B is appropriate.

what is the weight of a box that has a mass of 25 kg?
Answer:
Explanation:
The weight of an object is a measurement of how hard a force(in our case gravity) is pulling on an object. so W = mg, where W - is the weight. in our case W is G (Gravitational force) So G = mg => m = G/g => m = 25/9.8 => m = 2.5 kg. If you're problem states that weight is measured in kg, then it is definitely wrong. Weight is measured in Newtons and mass in kg. There are different system of units like gravitational,SI, MKS. I have seen in some text as slug as the unit of mass in gravitational system.So mass of 25 kg weight is 25/9.81 slug of mass.
Answer:
245.18 newtons
Explanation:
For example,
10 kg times 9.8 N/kg equals
98 N.

wooden block has a mass of 0.2 kg, has a specific heat of 710 J/(kg°C), and is a temperature of 20.0°C.
What is the block’s final temperature if its thermal energy increases by 2130 J?
Answer:
The final temperature is 35 °C.
Explanation:
Given that,
Mass of the wooden block, m = 0.2 kg
The specific heat of the block, c = 710 J/(kg°C)
Initial temperature, [tex]T_i=20^{\circ} C[/tex]
Thermal energy, Q = 2130 J
We need to find the block's final temperature. The thermal energy due to change in temperature is given by :
[tex]Q=mc(T_f-T_i)\\\\T_i\ \text{is initial temperature}\\\\\dfrac{Q}{mc}=(T_f-T_i)\\\\T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{2130}{0.2\times 710 }+20\\\\T_f=35^{\circ} C[/tex]
So, the final temperature is 35 °C.
