an object of mass 8 kg is whriled round in a vertical circle of radius 2m with a constant speed of 6m/s .Then the maximum and mi
algol13

Answer:

Maximum Tension=224N

Minimum tension= 64N

Explanation:

Given

mass =8 kg

constant speed = 6m/s .

g=10m/s^2

Maximum Tension= [(mv^2/ r) + (mg)]

Minimum tension= [(mv^2/ r) - (mg)]

Then substitute the values,

Maximum Tension= [8 × 6^2)/2 +(8×9.8)] = 224N

Minimum tension= [8 × 6^2)/2 -(8×9.8)]

=64N

Hence, Minimum tension and maximum Tension are =64N and 2224N respectively

Technician a says heat transfer is always hot to cold. technician b says high pressure always flows to low pressure. who is corr
r-ruslan [8.4K]

Both the technician are correct.

All the driving force in the universe always flow from the higher body to lower body, until unless acted by external forces. Which means heat always flow from a hotter body to colder body, high pressure always flow to low pressure.

Therefore the both the technician are correct.

As the resistance of a circuit increases, the current will
Natalija [7]

As the resistance of a circuit increases, the current will decreases.

<h3>What is ohm’s law?</h3>

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

When all physical parameters and temperature are constant,

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

This current-voltage connection may be expressed mathematically by Ohm's law as;

V=IR

If the voltage is constant, the resistance of the circuit will be inversely proportional to the current.

Hence,as the resistance of a circuit increases, the current will decreases.

To learn more of the ohm's law, refer to the link;
