A construction worker pushes a wheelbarrow 15 m with a horizontal force of 17 N. How much work is done by the worker on the object?
Answer:
The work done by the worker on the object is 255 J
Explanation:
Work is defined as the force that is applied on a body to move it from one point to another.
When a net force is applied to the body or a system and this produces displacement, then that force is said to perform mechanical work. This work can be positive if the system gains energy or negative if the system loses energy.
In the International System of Units, work is measured in Joule. Joule is equivalent to Newton per meter.
The work is equal to the product of the force by the distance and by the cosine of the angle that exists between the direction of the force and the direction that travels the point or the object that moves.
In this case, the angle between the force and the displacement is 0 degrees. Then the cosine of 0 degrees will have a value of one. So work is calculated as the multiplication between force and distance:
W= 17 N* 15 m
Solving:
W= 255 J
The work done by the worker on the object is 255 J

what is the magnitude of the eletrostatic force on an electron by another electron when they are 0.10 meter apart?
Answer:
[tex]F=2.30\times 10^{-26}\ N[/tex]
Explanation:
The distance between two electrons, d = 0.10 m
We need to find the magnitude of the electrostatic force on an electron by another electron.
The electrostatic force between two charges is given by :
[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]
Substitute all the values,
[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]
So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].
It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.
What is the electrostatic force?
It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.
The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.
The given data in the problem is;
q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C
r is the distance between the two charge=0.10 m
The formula for the electrostatic force is given by;
[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]
Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

A 2.75 kg block is pulled across a flat, frictionless floor with a 5.11 N force directed 53.8° above horizontal. What is the total force acting on the block? (total force = N)
Answer:
F = 3.01 N
Explanation:
Given that,
Mass of a block, m = 2.75 kg
Force applied to the block, F = 5.11 N
It is directed 53.8° above horizontal.
We need to find the total force acting on the block. The force acting on it is given by :
[tex]F=F\cos\theta\\\\F=5.11\times \cos53.8\\F=3.01\ N[/tex]
So, 3.01 N of force is acting on the block.
3.01 works as the right answer

A7 lb bowling ball accelerates at a rate of 7 m/s2. If the net force on the bowling ball is
tripled, what will be its new acceleration? (1 point)
a. 2.3 m/s2
b. 7 m/s2
c. 14 m/s2
d. 21 m/s2
Answer: c
Explanation:
If the net force on the bowling ball is tripled, its new acceleration is 21 m/s². The correct option is d.
What is force?The force is the action of push or pull which can move or stop the object.
The initial force is F = mass x acceleration
F = 3.17515 kg x 7 m/s²
F = 22.23 N
When the net force is tripled, the new acceleration will b e
3 x F =m x a'
3 x 22.23 = 3.17515 x a'
a' = 21.003 m/s²
Thus, the new acceleration is 21 m/s². The correct option is d.

While playing a video game on your laptop, the laptop gets very hot. Which Thermodynamics Law does this exemplify?
Answer
The dedicated graphics card is used when performing hardware-intensive tasks so as to ensure efficiency and balanced performance. However, it uses more power and thus produces more heat. When the cooling system is not sufficient or the room is not well ventilated, your PC begins to overheat while playing games. Explanation: How does the second law of thermodynamics relate to the direction of heat flow? Heat of itself never flows from a cold object to a hot object. ... The second law expresses the maximum efficiency of a heat engine in terms of hot and cold temperatures. one of these answers i am not sure

Calculate acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds.
Answer:
acceleration = 0.013 m/s²
Explanation:
formula for acceleration is
a = (v-u) / t
a= (0.7-0.3) / 30
= 0.013
The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²
Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:
[tex]a=\frac{v-u}{t}[/tex]
v is the final speed = 0.7m/s
u is the initial speed = 0.3m/s
t is the time taken = 30seconds
Substitute the given values into the formula:
[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]
Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Explain the challenges in developing an accurate rating system for earthquakes. What kinds of variables are there?
Answer:
In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. Let's take a look at the latter two (soil and buildings) and how they interact.
The challenge in developing an accurate rating system for earthquakes is due to complicated relationship between variables such as magnitude and intensity of earthquake.
Earthquakes are associated with magnitude and intensity.
The challenge in developing an accurate rating system for earthquake is due to complicated relationship and dependency between the magnitude and intensity of the earthquake.
