Physics
1 answer:
Lorico [155]3 years ago
8 0

Answer:

75

Explanation:

Here,

Hypotenuse (h)= X

base (b)= 72

perpendicular(p)=21

Now, h2=P2 + B2

x2 = (21×21) + (72×72)

x2= 441 + 5184

x2= 5625

X= √ 5625

X= 75

All traditional oriental medicine recognizes that an energy force called _____ flows through the body.
valentina_108 [34]

All traditional oriental medicine recognizes that an energy force called Qi flows through the body.

Traditional Chinese medicine is predicated on the idea that qi, or the body's life force, travels along meridian channels and maintains equilibrium in a person's physical, mental, emotional, and spiritual well-being. The Feldenkrais technique is a type of somatic education that combines focused attention and gentle movement to improve human function and mobility. You can broaden your range of motion, boost your comfort level, and enhance your flexibility and coordination by using this method. This could involve your food, your workout routine, psychotherapy, relationship counseling, and more. therapies that are complementary or alternative, including acupuncture, chiropractic adjustments, homeopathy, massage, naturopathy, and others.

A metal wire of resistance 2.30 10-8 is cut into two equal pieces that are then connected side by side to form a new wire the le
Elena-2011 [213]

Equal parallel resistors are governed by the formula


R = r^2/(2r) = r/2


r = 2.30 * 10^-8 ohms which is very tiny.


R = 2.30 *10^-8 / 2

R = 1.15 * 10^-8 ohms. <<<< Answer

How do particles move in the different states of matter
sertanlavr [38]
The particles in a solid are tightly packed and the particles do not move
The particles of liquid is less tightly packed and move with lesser kinetic energy than solids
The particles of gases are least tightly packed and the particles move around freely with the least kinetic energy than solids and liquids

Calculate the length of wire.<br>​
galben [10]

Answer:

L = 169.5 m

Explanation:

Using Ohm's Law:

V = IR

where,

V = Voltage = 1.5 V

I = Current = 10 mA = 0.01 A

R = Resistance = ?

Therefore,

1.5 V = (0.01 A)R

R = 150 Ω

But the resistance of a wire is given by the following formula:

R = \frac{\rho L}{A}

where,

ρ = resistivity = 1 x 10⁻⁶ Ω.m

L = length of wire = ?

A = cross-sectional area of wire = πr² = π(0.6 mm)² = π(0.6 x 10⁻³ m)²

A = 1.13 x 10⁻⁶ m²

Therefore,

150\ \Omega = \frac{(1\ x\ 10^{-6}\ \Omega .m)L}{1.13\ x\ 10^{-6}\ m^2}\\\\L = \frac{150\ \Omega(1.13\ x\ 10^{-6}\ m^2)}{1\ x\ 10^{-6}\ \Omega .m}\\\\

<u>L = 169.5 m</u>

A rock hits the ground at a speed of 15 m/s and leaves a hole 50 cm deep. After it hits the ground, what is the magnitude of the
garik1379 [7]

Answer:

B) 225 m/s^2

Explanation:

The rock hits the ground at 15m/s and travels 50cm=0.5m through the ground until it stops.

The acceleration is supposed to be uniform, so the formula we have to use is v^2=v_0^2+2ad, which for acceleration is:

a=\frac{v^2-v_0^2}{2d}

Taking the <em>downwards direction as positive</em> (the direction of traveling, so the initial velocity and displacement will be positive), substituting our values for that movement we have:

a=\frac{v^2-v_0^2}{2d}=\frac{(0m/s)^2-(15m/s)^2}{2(0.5m)}=-255m/s^2

Where the <em>negative sign indicates that it is pointing upwards.</em>
