calculate the deceleration of a snowboarder going up 5° slope assuming to go fission affection for waxed wet on wet snow
The deceleration of a snowboarder going up is 1.8 m / s²
We know that,
F = m * a
[tex]f_{k}[/tex] = μ[tex]_{k}[/tex] * [tex]F_{N}[/tex]
F = Force
m = Mass
a = Acceleration
[tex]f_{k}[/tex] = Kinetic frictional force
μ[tex]_{k}[/tex] = Co-efficient of kinetic friction
[tex]F_{N}[/tex] = Normal force
θ = 5°
μ[tex]_{k}[/tex] = 0.1
Since the snowboarder is going up the hill at an angle of 5°, the weight of the snowboarder does not align with the traditional y-axis direction. So resolving the weight into horizontal and vertical components.
sin 5° = - [tex]W_{x}[/tex] / W
[tex]W_{x}[/tex] = - W sin 5°
cos 5° = - [tex]W_{y}[/tex] / W
[tex]W_{y}[/tex] = - W cos 5°
[tex]f_{k}[/tex] = 0.1 ( [tex]W_{y}[/tex] )
[tex]f_{k}[/tex] = - 0.1 ( W cos 5° )
Σ [tex]F_{x}[/tex] = m [tex]a_{x}[/tex]
[tex]W_{x}[/tex] + [tex]f_{k}[/tex] = m [tex]a_{x}[/tex]
- W sin 5° - 0.1 ( W cos 5° ) = m [tex]a_{x}[/tex]
- W ( sin 5° + 0.1 cos 5° ) = m [tex]a_{x}[/tex]
- m g ( sin 5° + 0.1 cos 5° ) = m [tex]a_{x}[/tex]
- 9.8 ( sin 5° + 0.1 cos 5° ) = [tex]a_{x}[/tex]
[tex]a_{x}[/tex] = - 1.8 m / s²
Deceleration is the negative acceleration. When an object slows down it has deceleration. Kinetic friction is the frictional force created due to an object's motion.
Therefore, the deceleration of a snowboarder going up is 1.8 m / s²

Which of the following elements is likely to form an ionic bond with potassium?
Chlorine is likely to form an ionic bond with potassium.
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to generate chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds.
The main interaction in ionic compounds is ionic bonding, a type of chemical bonding that involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.
When a metal and a non-metal react, an ionic bond is created.
To establish an ionic bond, the metal loses electrons (donates them), whereas non-metals receive electrons (accept them).
Chlorine (Cl) is a non-metal, whereas potassium is a metal. As they interact to create an ionic bond, potassium donates one electron while chlorine accepts one.
The correct option is (A).

No, the words can be interpreted in one way only:

* If there is a single b (or the first b), then
if there is an even number of a's (including 0) before the b, this b is denoted as the start of (baa) and the a's before it is factored in one way as groups of (aa).
if there is an odd number of a's before the b, this b is a part of (aba) and the a's before it is factored in one way as groups of (aa).
* If there is a second b, then if the first b was denoted as a part of (baa), then if there is an even calculated numbers of a's between the b's, then
the second b is part of (baa), and the a's in between are factored in just one way as groups of (aa).
if there is an odd number present that is a's between the b's, then
this second b is denoted as a part of aba, and the a's in between are factored to be in one way as groups of (aa).
if the first b was part of (aba), then
if there is taken to be an even number of a's between the b's, then
the second b is part of (aba), and the a's in between are factored in one way as groups of (aa).
if there is an odd number of a's between the b's, then

A metal bowl with a weight of 1.05 n is placed in a larger kitchen container filled with soybean oil. how much soybean oil must the bowl displace in order to float? for reference, the mass density of soybean oil is about 917 g/liter and its weight density is about 8,99 n/liter. please give your answer in liters
The volume of soybean oil displaced by the boat to float is 0.00011 liters or 1.1 x 10^-4 liters.
An object floating in a liquid follows Archimedes’ Principle.
According to the Archimedes Principle, the amount of fluid displaced by the body is equal to its weight.
So, the buoyant force applied by the liquid should be equal to the weight of the bowl.
Hence
Weight of bowl = Buoyant Force of Soybean Oil
Mg = V(ρ)(g)
Here V = volume of soybean oil
ρ = density of soybean oil
1.05 = V x 917 x 9.8
The volume(V) comes out to be 0.00011 liters.
Thus, the volume of soybean oil displaced by the bowl to float is 0.00011 liters or 1.1 x 10^-4 liters.

By ideal gas approximation, the final volume is 6.84 liters.
We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does newton’s second law apply to a situation in which there is no net force? select the best explanation.
Newton's second law does apply to a situation in which there is no net force as having a net force of zero will produce an acceleration having 0.
According to Newton's second law, the acceleration of an object depends upon two variables- the mass of the object and the net force acting on the object. Here, the acceleration of an object is directly proportional to the force acting on it and inversely proportional to the mass of that object. The net force applied is equal to the sum of all the forces acting on an object.
In a situation where the net force applied is zero, the object having a mass would have zero acceleration. This means that the object would have zero velocity and would be constant.
This depicts that Newton's second law can be applied to every situation where there is a net force applied, or not. Even if there is no net force, this law can still be applied.

Height above the top of Tom's window the ball was dropped= 1.31m
Given that,
The height of window (s) = 1.50m
Time(t) = 0.240s
We have to find the height, and for this, we have to find the velocity using the equation of motion:
s = ut + 1/2 g[tex]t^{2}[/tex]
By putting the value of h and t in the equation
1.50 = u × 0.240 + 1/2 × 9.8 × [tex]0.240^{2}[/tex]
1.50 = u × 0.240 + 0.28224
u = (1.50 - 0.28224) / 0.240
u= 1.21776 / 0.240
u= 5.074

A ball is dropped from an upper floor, some unknown distance above Tom's apartment. As he looks out of his window, which is 1..50 m tall, Tom observes that it takes the ball 0.240 s to traverse the length of the window. Determine how high ℎ above the top of Tom's window the ball was dropped. Ignore the effects of air resistance.
Is the magnetic field inside the loop increasing in strength, decreasing in strength, or steady?
There is a induced current in the conducting loop shown in the figure. According to the Lenz law, the magnetic field inside the loop is decreasing in strength.
State Lenz law.
The induced electromotive force (emf) with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in to ensure that the original flux is maintained throughout the loop when the current flows in it.
How is Lenz’s law conservation of energy?
Lenz’s law is based on the law of conservation of energy. The induced current is always opposed by the cause that produces it. Hence, there is extra work done against the opposing force. The work done against the opposing force results in the change in the magnetic flux and hence the current is induced. Hence the law of conservation of energy is satisfied.

A partial sum of an arithmetic sequence is given. find the sum. 5 9 13 . . . 381
The sum arithmetic sequence is 18,335 of a partial sum of an arithmetic sequence is given 5 9 13 . . . 381
Calculation
d = 9-5 = 4
a = 5
[tex]a_n[/tex] = 5 + 4(n -1) = 381
= 5 + 4n -4 = 381
= 4n +1 = 381
= 4n = 380
= n = 380/4
= 95
Now,
[tex]S_{95}[/tex] = [tex]95(\frac{5 + 381}{2} )[/tex]
= 95 × 193
= 18,335
What is arithmetic sequence?The series where the common difference between any two next words stays constant is known as an arithmetic sequence. Let's review what a sequence is. A collection of numbers that follow a pattern is called a sequence. As an illustration, the numbers 1, 6, 11, 16,... are an arithmetic sequence because they follow a pattern in which the preceding term is multiplied by 5 to produce each subsequent number. There are two formulas for arithmetic sequences.
