The acceleration when a 60 kg man in bosun's chair exerts a pull, is -3.76 m/s².
<h3>What is acceleration?</h3>
The acceleration is the time rate of change of velocity.
Given the mass of man m= 60 kg and pull = 363N
According to the equilibrium conditions, 3T -mg =ma
The pull is equal to the tension 3T =363 N
Substituting the values, we get
363N - 60x 9.81 = 60a
a =-3.76m/s²
Thus, the acceleration is -3.76m/s².

The part of the electromagnetic spectrum closest to radio waves is <u> microwaves</u>.
The wavelength of radio waves ranges from 10 cm to more than 1 km. The part of the electromagnetic spectrum that occurs closest to the radio waves is called the microwave region.
Microwaves have wavelengths ranging from around 1 mm to 10 cm.
The waves overlap in the region of 10 cm.
Thus, the region of electromagnetic spectrum closest to radiowaves is <u> microwaves.</u>

When marble is flicked off the edge of a table then the at the instant it will move off the table the velocity is horizontal while due to force of gravitation the marble will start accelerating downwards.
So here we will say that the velocity of marble will remain constant through out the motion in X direction as there is no force in that direction
While in Y direction the marble will have gravitational force due to which marble will accelerate downwards
So the path of the marble will be parabolic path
hence the correct answer will be
<em>A.
</em>
<em>Only one continuous force is acting on the marble.</em>
