11.86 years, or around that time it would take about 12 years.

If P = 4.00î + 3.00k, P · Q = 17.0, and P ✕ Q = −6.00ĵ, determine the vector Q.

Butoxors [25]

let the vector Q is given as

$\vec Q = a\hat i + b\hat j + c\hat k$

given that

$P X Q = -6\hat j$

here we know that

$P = 4\hat i + 3 \hatk$

now by above equation

$(4\hat i + 3\hat k) X (a\hat i + b\hat j + c\hat k) = - 6\hat j$

$4b\hat k - 4c\hat j + 3a\hat j - 3b\hat i = - 6\hat j$

so by comparing both sides

b = 0

4c - 3a = 6

also we know that

$a^2 + b^2 + c^2 = 17^2$

$a^2 + 0 + (1.5 + 0.75a)^2 = 289$

by solving above equation

a = 12.85 and c = 11.14

so the vector Q is given as

$Q = 12.85\hat i + 11.14\hat k$

Where is parallel circuits used?

suter [353]

Answer:

if one bulb burns out, the other bulbs in the fixture continue to operate. Other uses include an electronic OR gate, where two switches are in a parallel circuit: one of the switches must be closed for the circuit to function.

A 10-kilogram bicycle is traveling at a speed of 2m/s. what is the bike's kinetice energy?

madam [21]

The kinetic energy of an object of mass m moving with speed v is given by:
$K= \frac{1}{2}mv^2$
For the bicycle in our problem, $m=10 kg$ and $v=2 m/s$ , so the kinetic energy is
$K= \frac{1}{2}(10 kg)(2 m/s)^2=20 J$

Explain why gases are more compressible than solid

Oduvanchick [21]

Answer:

If we put pressure on a solid or a liquid, there is essentially no change in volume. ... The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
