Answer:

\boxed {Density = 4800 kg/m^{3}}

Explanation:

<u>Formula</u> :

\boxed {Density = \frac{Mass (kg)}{Volume (m^{3})}}

<u>Convert volume into standard unit</u> :

⇒ 250000 cm³ × 10⁻⁶

⇒ 0.25 × 10⁶ × 10⁻⁶

⇒ 0.25 m³

<u>Solve for density</u> :

⇒ Density = 1200 kg / 0.25 m³

⇒ Density = 1200 × 4 kg/m³

⇒ Density = 4800 kg/m³

Answer:

Explanation:

Voltage and Current relation is given by V=IR
I=9A

R=4Ohm

V=IR
V=9x4=36Volts

Resistance = 4 Ohm

Current = 9 Ampere

Voltage = 36 Volts

Which object has the least momentum? object a: m = 1 kg, v = 100 m/s object b: m = 10 kg, v = 12 m/s object c: m = 0.5 kg, v = 1
nirvana33 [79]
A = 1*100 = 100 Ns
b = 10 * 12 = 120 Ns
c = 0.5*1000 = 500 Ns
d = 100 * 2 = 200 Ns

a has least momentum

Using a radar gun, you emit radar waves at a frequency of 6.2 GHz that bounce off of a moving tennis ball and recombine with the
Keith_Richards [23]

Answer:

23.4 m/s

Explanation:

f = actual frequency of the wave = 6.2 x 10⁹ Hz

f_{app} = frequency observed as the ball approach the radar

f_{rec} = frequency observed as the ball recede away from the radar

V = speed of light

v = speed of ball

B = beat frequency = 969 Hz

frequency observed as the ball approach the radar is given as

f_{app}=\frac{f(V+v)}{V}                                 eq-1

frequency observed as the ball recede the radar is given as

f_{rec}=\frac{f(V-v)}{V}                                  eq-2

Beat frequency is given as

B = f_{app} - f_{rec}

Using eq-2 and eq-1

B = \frac{f(V+v)}{V}- \frac{f(V-v)}{V}

inserting the values

969 = \frac{(6.2\times 10^{9})((3\times 10^{8})+v)}{(3\times 10^{8})}- \frac{(6.2\times 10^{9})((3\times 10^{8})-v)}{(3\times 10^{8})}

v = 23.4 m/s
