A 1.35 kg block is pulled across a

Physics

Flura [38]2 years ago

5 0

Answer:

F=ma

3.07=1.35(a)

3.07/1.35 = a

a=2.27m/s^2

Explanation:

Since the question gives us both the force and mass of the object we can use the f= ma equation and just plug in both the force and mass and just solve for acceleration. I believe the degree listed in the question is just there to throw you off.

A copper wire 1.0 meter long and with a mass of .0014 kilograms per meter vibrates in two segments when under a tension of 27 Ne

Furkat [3]

Answer:

the frequency of this mode of vibration is 138.87 Hz

Explanation:

Given;

length of the copper wire, L = 1 m

mass per unit length of the copper wire, μ = 0.0014 kg/m

tension on the wire, T = 27 N

number of segments, n = 2

The frequency of this mode of vibration is calculated as;

$F_n = \frac{n}{2L} \sqrt{\frac{T}{\mu} } \\\\F_2 = \frac{2}{2\times 1} \sqrt{\frac{27}{0.0014} }\\\\F_2 = 138.87 \ Hz$

Therefore, the frequency of this mode of vibration is 138.87 Hz

Paha777 [63]

Answer:False

Explanation:

The given statement is false

because the sine ratio is the ratio formed by the side opposite the acute angle to the hypotenuse

$\sin (acute\ angle)=\frac{Perpendicular}{hypotenuse}$

When a current flows through an ionic liquid such as salty water, the moving charges are?

expeople1 [14]

In salty water ions are produced by the salt

here salt is NaCl

so it will break in Na⁺ and Cl⁻

They carry the current

Na⁺ moves towards cathode and Cl⁻ moves towards anode

So current is carrying by ions which are Na⁺ and Cl⁻
