Answer:

It is called so because it is applicable on all bodies having mass, and the bodies will be governed by the same law, that is newton's law of gravitation. Thus, as it is applicable universally, it is called as universal law.

A note is being played on a string on a guitar. The string is then pushed to the side while still in contact with the same fret.

Brut [27]

Answer:

See explanation

Explanation:

- When the string is pressed on a particular fret, the note is the same. That's because the string will sound from bridge to that fret-wire. It's always the same distance, so will always be the same note.

- Frets is that it splits the fingerboard into discrete diatonic parts, and well made fret-boards will mean the same note gets played on the same fret on the same string every time.

What is the amount of heat, in Sl units, necessary to melt 1 lb of ice?

likoan [24]

Answer:

Heat required to melt 1 lb of ice is 151.469 KJ

Explanation:

We have given mass of ice = 1 lb

We know that 1 lb = 0.4535 kg

Latent heat of fusion for ice =334 KJ/kg

Amount if heat for fusion of ice is given by

$Q=mL$ , here m is mass of ice and L is latent heat of fusion

So heat $Q=mL=0.4535\times 334=151.469kj$

So heat required to melt 1 lb of ice is equal to 151.469 KJ

A student is helping her teacher move a 9.5 kg box of books. What net sideways force must she exert on the box to slide it acros

Lilit [14]

As we know that mass of the box is given as

m = 9.5 kg

acceleration of the box is given as

$a = 1 m/s^2$

so by Newton's II law we can say

$F = ma$

now we can substitute all the values in it

$F = 9.5 \times 1$

$F = 9.5 N$

So it required 9.5 N force to slide it

A circuit is built based on this circuit diagram. What is the equivalent resistance of the circuit?

Dmitry_Shevchenko [17]

The three resistors are connected to the same points of the circuit, so they are in parallel configuration. The equivalent resistance of 3 resistors in parallel is given by:
$\frac{1}{R_{eq}}= \frac{1}{R_1}+ \frac{1}{R_2}+ \frac{1}{R_3}$
If we plug the values of the resistances into the formula, we find
$\frac{1}{R_{eq}}= \frac{1}{3.0 \Omega}+ \frac{1}{6.0 \Omega}+ \frac{1}{9.0 \Omega}= \frac{6+3+2}{18.0 \Omega} = \frac{11}{18.0 \Omega}$
From which we find the equivalent resistance:
$R_{eq} = \frac{18.0}{11} \Omega =1.6 \Omega$

So, the correct answer is B.
