Answers
a. The support reaction forces at the smooth collar A are Ax = 800 N and Ay = 600 N,
b. The support reaction moments at the smooth collar A are M(A)x = -1600Nm, M(A)y = 0Nm, and M(A)z = 400Nm
C. the normal reaction at the roller support B is B- = 600N.
The value of Ax = 800 N and Ay = 600 N , M(A)x = -1600Nm, M(A)y = 0Nm, and M(A)z = 400Nm B- = 600N.
The support reaction forces at the smooth collar A can be determined using equations of equilibrium:
F1 + F2 = Ax + Ay and F1x = Ax.
Therefore, Ax = 800 N and Ay = 600 N.
The support reaction moments at the smooth collar A can be determined using the moments equation of equilibrium: M(A)x + M(A)y + M(A)z = 0.
Substituting in the values for Ax and Ay, we can solve for the support reaction moments: M(A)x = -1600Nm, M(A)y = 0Nm, and M(A)z = 400Nm.
The normal reaction at the roller support B can be determined using equations of equilibrium:
F1 + F2 + B- = 0 and Ay = B-.
Therefore, B- = 600N.
In summary, the support reaction forces at the smooth collar A are Ax = 800 N and Ay = 600 N, the support reaction moments at the smooth collar A are M(A)x = -1600Nm, M(A)y = 0Nm, and M(A)z = 400Nm, and the normal reaction at the roller support B is B- = 600N.

wire 1 has a resistance r1. wire 2 is made of the same material, is half as long and has half the diameter. what is the ratio r2/r1? r2/r1
Answers
The resistance of the wire is R1
Let L be the length of the wire and d be the diameter
Then resistance
R1 = ρL/A
Where ρ is the resistivity of the material
A is the crossectional area = πd2/4
As the material is not changed, ρ does not changes
new length L' = L/2
new diameter d' = d/2
Therefore the new resistance is
R2 = ρL'/A'
R2 = ρ(L/2)/(A/4) (A' = π(d/2)2/4)
R2 = 2 ρL/A
R2 = 2R1
R2/R1 = 2
What is resistance?
The material a thing is constructed of has a significant impact on how resistant it is. Electrical insulators like rubber have extremely high resistance and poor conductance tendencies, whereas electrical conductors like metals have extremely low resistance and high conductivity tendencies. Conductivity or resistivity are used to measure this relationship. However because resistance and conductance are extensive rather than intense qualities, they depend on the size and shape of an object as well as the type of the material. For instance, if a wire is long and thin, its resistance will be higher, and if it is short and thick, it will be lower. Except for superconductors, which have a resistance of zero, all objects resist electrical current.To know more about resistance, click the link given below:

Which form of electromagnetic radiation would be blocked in the stratosphere by ozone?
Select one:
A. cosmic rays
B. ultraviolet
C. infrared
D. microwaves
E. visible light
Answers
Ultraviolet is correct answer .UV radiation is the type of electromagnetic energy that ozone would block in the stratosphere.
The ozone layer in the stratosphere blocks ultraviolet (UV) radiation, which is a form of electromagnetic radiation. This is important because UV radiation can be harmful to living organisms, including humans, causing skin damage and increasing the risk of skin cancer.
The majority of the sun's dangerous ultraviolet (UV) radiation, especially UV-B rays, are absorbed by ozone in the stratosphere, which serves as a natural filter. In addition to causing skin cancer, cataracts, and other health issues, UV radiation can be dangerous to living things. The majority of UV-B radiation falls within the 200–300 nanometer (nm) band of UV light that is absorbed by ozone. This is one of the reasons the ozone layer is crucial for life on our planet because it shields it from the damaging effects of UV radiation. Ozone in the stratosphere does not appreciably absorb other types of electromagnetic radiation, such as cosmic rays, infrared, microwaves, and visible light.

A car of mass 900 Kg is moving with a velocity of 10 m/s. It is brought to rest at 25 m distance by applying the brakes. Calculate the acceleration. Why is it negative? How much force is required to stop the car?
Answers
Answer:
Assumption: the acceleration of this vehicle is constant until it comes to a stop.
Acceleration: \((-2)\; \rm m\cdot s^{-2}\).
The acceleration of this vehicle is negative because the velocity of this vehicle is decreasing over time.
Explanation:
Let \(u\) denote the initial velocity of this vehicle. \(u = 10\; \rm m\cdot s^{-1}\).Let \(v\) denote the final velocity of this vehicle. \(v = 0\; \rm m\cdot s^{-1}\) as the vehicle has come to a stop.Let \(x\) denote the displacement of this vehicle. \(x = 25\; \rm m\).Let \(a\) denote the acceleration of this vehicle. The value of \(a\!\) needs to be found.Assume that the acceleration of this vehicle, \(a\), is constant. The SUVAT equations would apply.
The time \(t\) required for braking is neither given nor required. Hence, make use of the SUVAT equation \(v^{2} - u^{2} = 2\, a\, x\) to relate \(u\), \(v\), \(a\), and \(x\!\).
Rearrange this equation to find an expression for \(a\), the acceleration of this vehicle:
\(\begin{aligned}a &= \frac{v^{2} - u^{2}}{2\, x} \\ &= \frac{(0\; \rm m\cdot s^{-1})^{2} - (10\; \rm m \cdot s^{-1})^{2}}{2\times (25\; \rm m)} \\ &= \frac{0^{2} - 10^{2}}{2 \times 25}\; \rm m \cdot s^{-2} \\ &= -2\; \rm m\cdot s^{-2}\end{aligned}\).
When the rate of change of a value is greater than \(0\), that value would become larger over time.When the rate of change of a value is equal to \(0\), that value would be constant.When the rate of change of a value is smaller than \(0\), that value would become smaller over time.
Acceleration is the rate at which velocity changes over time.
The velocity of the vehicle in this question is getting smaller over time. Hence, the rate of change of the velocity of this vehicle (that is, the acceleration of this vehicle) would be a negative number.

Suppose the activity of a sample of radioactive material was 100bq at the start. What would you divide 100bq by to obtain the activity n half lives after the start!
Formula please for Isaac physics half life section
Answers
To calculate the activity of a radioactive material n half-lives after the start, you would divide the initial activity by \(2^n\).
The formula for calculating the activity of a radioactive material after a certain number of half-lives is given by:
A = \(A_0*(\frac{1}{2} )^n\)
where A is the activity of the sample after n half-lives, A0 is the initial activity, and n is the number of half-lives.
In this case, we want to know the activity n half-lives after the start, so we can substitute n for the number of half-lives in the formula and simplify:
A = \(A_0*(\frac{1}{2} )^n\)
A = \(100*(\frac{1}{2} )^n\)
To find the activity n half-lives after the start, we divide the initial activity (100 Bq) by 2^n, where n is the number of half-lives. So the formula for the activity after n half-lives can be written as:
A = \((\frac{A_0}{2} )^n\)
A = \((\frac{100}{2} )^n\)

The relation is:
● r = s^2 / t^2
Triplind s means multiplying it by 3. Since it's an equation we should multiply both sides by the same number
Let k be the number we should multiply by r
●k* r = (3s)^2 / t^2
●k* r = 9s^2 /t^2
We have multiplied s^2 by 9 so we should do the same for r.
k = 9

Doubling t means multiplying it by 2.
Let x be the number we shoukd multiply by r.
● x* r = s^2/(2t)^2
● x*r = s^2/ 4t^2
We have multiplied t^2 by 4 so we should do the same for r.

A converging mirror with a focal length of 7cm is held 4cm from your face. Determine the image location?
Answers
The image is approximately 9.33 cm away from the mirror, on the object's side.
To determine the image location formed by a converging mirror, we can use the mirror equation:
1/f = 1/d_o + 1/d_i
where:
f is the focal length of the mirror,
d_o is the object distance (distance of the object from the mirror), and
d_i is the image distance (distance of the image from the mirror).
In this case, the focal length (f) is given as 7 cm, and the object distance (d_o) is 4 cm.
Plugging in the values into the mirror equation:
1/7 = 1/4 + 1/d_i
To find the image distance (d_i), we can solve for it:
1/d_i = 1/7 - 1/4
1/d_i = (4 - 7) / (4 * 7)
1/d_i = -3 / 28
Taking the reciprocal of both sides:
d_i = 28 / -3
d_i ≈ -9.33 cm
The negative sign indicates that the image formed by the converging mirror is virtual and located on the same side as the object.
Therefore, the image is approximately 9.33 cm away from the mirror, on the object's side.
