Answer: mass = 48.47 kg.

Explanation:

Formula : Weight = mg  , where m = mass of body , g= acceleration due to gravity .

Given: Weight  = 475 N

g= 9.8\ m/s^2

Substitute all values in formula ,  we get

475= m \times9.8\\\\\Rightarrow\ m = \dfrac{475}{9.8}\\\\\Rightarrow\ m \approx 48.47\ kg

Hence, his mass = 48.47 kg.

Letters A B, C and D represent locations on a bar magnet. Which location has the greatest magnetic force? (l) A (3) C ets (2) B
Elena L [17]
Answer: The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center. So it would be D.

The area of an equilaterla triangle is increasing at a rate of 5 m^2/hr. find the rate at witch the height is chganging when the
Lena [83]

The rate at which the height is changing is ( 5 / x ) m / hr

We know that,

Area of an equilateral triangle A = \sqrt{3} x^{2} / 4

h = \sqrt{3} x / 2

Where,

x = Side

h = Height

Given that,

dA / dt = 5 m^{2} / hr

h = \sqrt{3} x / 2

Differentiate both sides with respect to t

dh / dt = ( \sqrt{3}  / 2 ) ( dx / dt )

dx / dt = ( 2 /  \sqrt{3} ) ( dh / dt )

A = \sqrt{3} x^{2} / 4

Differentiate both sides with respect to t

dA / dt = ( \sqrt{3} / 4 ) ( 2x ) ( dx / dt )

5 =  ( \sqrt{3} / 4 ) ( 2x ) ( 2 /  \sqrt{3} ) ( dh / dt )

dh / dt = ( 5 / x ) m / hr

Rate of change of height is defined as the rate at which height of an object changes with respect to time. It is represented as dh / dt

Therefore, the rate at which the height is changing is ( 5 / x ) m / hr

Which one is correct and why?​
Gelneren [198K]

'A' and 'C' are exactly the same circuit, except the voltmeter's terminals are flipped.

'A' is the correct way to hook everything up.

If you start at the positive terminal of the battery, and follow the flow of current through the circuit and around to the negative terminal, you're following the path where the voltage gets lower and lower and lower all the way.

So each time you come to any device in the circuit ... whether it's a resistor or a meter ... you would be hitting the positive side of it first, and then the voltage where you come out on the other side of it would be lower.  

So the left side of the resistor is more positive, and the right side is more negative.  The voltmeter is connected correctly in 'A', but it's backwards in 'C'.  If you connect the voltmeter like in 'C' and turn things on, the voltmeter will try  to go <em>down</em> from zero.  You can't read the number on it, and It's possible that the voltmeter might be damaged.
