Question 1 (10 points)

Physics
1 answer:
blagie [28]2 years ago

The answer to 12g is equal to c) 1.2× 10¹⁶ g

Gram is the one thousandth of the kilogram which means 1g = 0.001kg

Gram is represented by g.

Femtogram is equal to 0.0000000000000001 grams or 10⁻¹⁵g.

Femtogram is represented by fg.

1 Femtogram = 10⁻¹⁵g

1g = 10¹⁵ fg

Now According to the question,

12g = 12 × 10¹⁵ fg

12g = 1.2× 10¹⁶ fg

Hence, 12g is equal to c)1.2× 10¹⁶ g

A golf ball (mass 0.045 kg) is hit with a club from a tee. The plot shows the force on the ball as a function of time in millise
almond37 [142]

Answer:

16.3 m/s

Explanation:

We are given that

Mass of golf ball=m=0.045 kg

We have to find the speed right after the hit.

b_1=(16-1)\times 10^{-3}=15\times 10^{-3} s

b_2=(12-6)\times 10^{-3}=6\times 10^{-3} s

Force,F=70 N

Change in momentum=Area of trapezium

Area of trapezium,A=\frac{1}{2}(b_1+b_2) h

Using the formula

m(v-u)=\frac{1}{2}(15+6)\times 10^{-3}\times 70

0.045(v-u)=\frac{1}{2}(21)\times 10^{-3}\times 70

v-u=\frac{1}{2}\times \frac{1}{0.045}\times 21\times 10^{-3}\times 70

v-u=16.3

Initial velocity of golf ball=u=0

v-0=16.3

v=16.3 m/s

Determine the power of 60 joules of work done in four seconds
zheka24 [161]
Power = (energy) / (time)

           =   (60 joules) / (4 seconds)

           =         15 joules/second

           =          15 watts

In an attempt to reduce the extraordinarily long travel times for voyaging to distant stars, some people have suggested travelin
Vika [28.1K]

Answer:

Explanation:

Let the required velocity of rocket be v .

We shall use the formula of time dilation to find the velocity of rocket .

t = \frac{t'}{\sqrt{1-\frac{v^2}{c^2} } }

t = 430

t' = 38

430=\frac{38}{\sqrt{1-\frac{v^2}{c^2} } }

\sqrt{1-\frac{v^2}{c^2} } }=\frac{38}{430}

1-\frac{v^2}{c^2} = .0078

\frac{v^2}{c^2} =.9922

\frac{v}{c} = .996

v  = .996 x 3 x 10⁸ m /s

= 2.988 x 10⁸ m /s

B )

Kinetic energy of rocket

= 1/2 m v²

= .5 x 20000 x (2.988 x 10⁸ )²

= 8.9 x 10²⁰ J .

C )

This energy is 8.9 times the energy requirement of United states in the year 2005 .

A single strain gage has a nominal resistance of 120 ohm. For a quarter bridge with 120 ohm fixed resistors, strain gauge factor
natita [175]

Answer:

Output voltage is 1.507 mV

Solution:

As per the question:

Nominal resistance, R = 120\Omega

Fixed resistance, R = 120\Omega

Gauge Factor, G.F = 2.01

Supply Voltage, V_{s} = 3\ V

Strain, \epsilon = 1000\times 10^{-6}\ strain

Now,

To calculate the output voltage, V_{o}:

WE know that strain is given by:

\epsilon = \frac{(R + R')^{2}V_{o}}{RR'V_{s}\times G.F}

Thus

V_{o} = \frac{RR'V_{s}\epsilon \times G.F}{(R + R')^{2}}

Now, substituting the suitable values in the above eqn:

V_{o} = \frac{120\times 120\times 3\times 1000\times 10^{-6}\times 2.01}{(120 + 120)^{2}}

V_{o} = 1.507\ mV

Most galaxies in the Universe are moving towards the Earth. True or False.
Morgarella [4.7K]

That's false.

There are billions of galaxies in the universe. A few of the nearest ones are moving TOWARD us, and ALL the rest are moving AWAY from us.

The farther a galaxy is from us now, the faster it's moving farther away.
