Answer:

I) 65000 g   II)24.325 hours  III)7500 m

Explanation:

I) 1 kg = 1000 g

65 kg = 65 * 1000 g = 65000 g

II) 1 hour = 3600 seconds

1 second = 1/3600 hours

87570 seconds = 87570 * 1/3600 hours =24.325 hours

III) 1 km = 1000 m

7.5 km = 7.5 * 1000 m = 7500 m

What is the half-life of an isotope if 125 g of a 500 g sample of the isotope remains after 3.0 years?
Troyanec [42]

Answer:

125 / 500 = 1/4    of the sample left after 3.0 yrs

1/2 * 1/2 = 1/4        sample has decayed thru 2 half-lives

2 * HL = 3

1 Half-Life = 1.5 yrs

The rate of rotation of the disk is gradually increased. The coefficient of static friction between the coin and the disk is 0.5
MrRissso [65]

Question is not complete and the missing part is;

A coin of mass 0.0050 kg is placed on a horizontal disk at a distance of 0.14 m from the center. The disk rotates at a constant rate in a counterclockwise direction. The coin does not slip, and the time it takes for the coin to make a complete revolution is 1.5 s.

Answer:

0.828 m/s

Explanation:

Resolving vertically, we have;

Fn and Fg act vertically. Thus,

Fn - Fg = 0 - - - - eq(1)

Resolving horizontally, we have;

Ff = ma - - - - eq(2)

Now, Fn and Fg are both mg and both will cancel out in eq 1.

Leaving us with eq 2.

So, Ff = ma

Now, Frictional force: Ff = μmg where μ is coefficient of friction.

Also, a = v²/r

Where v is linear speed or velocity

Thus,

μmg = mv²/r

m will cancel out,

Thus, μg = v²/r

Making v the subject;

rμg = v²

v = √rμg

Plugging in the relevant values,

v = √0.14 x 0.5 x 9.8

v = √0.686

v = 0.828 m/s

An electric heater is rated at 1500 W, a toaster at 750 W, and an electric grill at 1000 W. The three appliances are connected t
Varvara68 [4.7K]

Answer:

   I= 27.09 A

Explanation:

Power of electric heater = 1500W= 1.50*10³ W

Power of toaster = 750W = 7.5*10²W

Power of electric grill = 1000W =1*10³ W

Voltage = 120V

By using formula P=VI ie I = \frac{P}{V}

A) Current used by electric heater I₃ =\frac{1.50*10^3}{120}

                    I₃ = 12.5 A

B) Current used by toaster I₂ =\frac{750}{120}

                I₂ = 6.25 A

C) Current used by electric grill I₃ = \frac{1000}{120}

                   I₃ = 8.34 A

Current used by all three appliances is

       I=I₁+I₂+I₃

        I=12.5+6.25+8.34

         I= 27.09 A
