What effect does the diameter of the string have on the lever arm? explain why we can ignore this effect
The effective lever arm will be enhanced if we utilize a big diameter string.
What is Lever Arm?The perpendicular distance from the axis of rotation to the force's line of action is specified as the lever arm.
When a big diameter string is utilized, the effect of the diameter on the string of the lever arm will be enhanced.
This is due to the reason that if the radius of the pulley is R and the radius of the string is r, then the effective lever arm becomes R+r.
If the radius,r of the string is very minute such that its addition to the radius of the pulley, R will hardly make a change to the effective lever arm, then it is avoided. However, if the radius of the string is a big number then it can not be avoided as it can make significant errors in the calculation of the effective lever arm.

In physics, a transverse wave is a wave whose oscillations are perpendicular to the direction of the wave's advance. This is in contrast to a longitudinal wave which travels in the direction of its oscillations. Water waves are an example of transverse wave.
Transverse waves commonly occur in elastic solids due to the shear stress generated; the oscillations in this case are the displacement of the solid particles away from their relaxed position, in directions perpendicular to the propagation of the wave. These displacements correspond to a local shear deformation of the material. Hence a transverse wave of this nature is called a shear wave. Since fluids cannot resist shear forces while at rest, propagation of transverse waves inside the bulk of fluids is not possible.

Alice's speed relative to the water should be 0.6 m/s in order to target the spot 90 meters south of the starting point on the bank of the other side.
What is relative velocity?Relative velocity refers to the velocity of an object with respect to another observer.
Velocity is speed in a given direction and is a vector quantity.

What magnitude net force is required to accelerate a 1200-kg car uniformly from 0 m/s to 27.0 m/s in ?
Magnitude of Net force Required to accelerate a 1200kg car uniformly from 0m/s to 27m/s in 10s is 3240N.
Force can be found out using the relation of Force, mass and acceleration.
The relation of Force, mass and acceleration is as follows:
∴ Force = Mass × Acceleration
⇒ Force = 1200kg × Acceleration
Given:
Mass = 1200kg
Final Velocity = 27m/s
Initial Velocity = 0m/s
time = 10s
Now, to find out the acceleration we can use the first equation of motion:
∴ Final Velocity = Initial Velocity + Acceleration × time
⇒ 27 = 0 + 10a
⇒ a = 2.7m/s²
Putting acceleration in the above mentioned equation,

How much heat in joules will it take to raise the temperature of a 100. 0 g piece of copper from 18°c to 35°c? the specific heat capacity of copper is 0. 385 j ⁄ g · °c
The amount of heat generated is 654.5 joules.
q=mCΔT
Given,
m=100, C=0.385 j ⁄ g · °c, [tex]T_{1} =18^{0}C , T_{2} =35^{0} C[/tex],
q=100*0.385*(35-18)= 654.5 j
HeatHeat is defined as energy that is transferred to or from a thermodynamic system by means other than thermodynamic work or the movement of matter (e.g. conduction, radiation, and friction). Similar to thermodynamic work, heat transfer affects a system's surrounds in addition to the system itself; as a result, it is not a characteristic of the system alone, even while it helps to change the internal energy of the system, which is a property of the system alone. This differs from the common linguistic usage of the word "heat" as a system feature in and of itself. The quantity of energy that is transported as heat in a process is the amount of energy that has been transferred minus any thermodynamic work that has been done and any energy that has been contained in the substance being moved.

A compound is discovered and its molecular weight is determined to be 526g/mol. however, one of the elements has not yet been identified. what is the missing element, x, in batio9(x7)?
Sulphur
The missing element is sulphur
Here the compound is composed of element X and chlorine.
it is given,
XCl (6) ----> 6Cl
mass = 13.1%
it is X and Cl = 100%-13.10%
= 86.90%
chlorine = 86.90
X = 13.10
We assume 100g of sample
so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.
now we split that chlorine into two moles of chlorine.
Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that. We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six. we discover that we have 0.4086 moles of X when we divide this by six.We obtain those moles of X from 13.10 g of X. Given that Mueller masses grams per mole, I can compute the molar mass.13.10 grams of X are contained in 0.4086 moles of X. Or, to put it another way, each remote has a molar mass of 32–06 grams. The element with this molar mass is sulfur, as I can see from the periodic table. Okay, so the element we're looking for in this situation is sulfur.To learn more about finding missing element visit;
