Answer:

Explanation:

Equal to the sum of the densities of both substances

Equal to the difference in the densities of both substances

of which I cannot predict anything about its value

of an intermediate value to both substances which will depend on which substance is in greater quantity

Answer:

Explanation:

according to einstein's formulae E=mc2 1kg of mass is equivalent to (9joules when rounded off )

in this situation we ignore the bridge height and work hand in hand with the relativity and force

so...if you do the conversion you will find the suitable answer which is 16.9J

Why will humans feel lighter on mars?

kotykmax [81]

Because Mars is further from the sun than Earth is, thus the gravitational pull is not as great on Mars as it is on Earth, making us lighter :)

To practice Problem-Solving Strategy 15.1 Mechanical Waves. Waves on a string are described by the following general equation y(

NeX [460]

Answer:

The transverse displacement is $y(1.51 , 0.150) = 0.055 m$

Explanation:

From the question we are told that

The generally equation for the mechanical wave is

$y(x,t) = Acos (kx -wt)$

The speed of the transverse wave is $v = 8.25 \ m/s$

The amplitude of the transverse wave is $A = 5.50 *10^{-2} m$

The wavelength of the transverse wave is $\lambda = 0540 m$

At t= 0.150s , x = 1.51 m

The angular frequency of the wave is mathematically represented as

$w = vk$

Substituting values

$w = 8.25 * 11.64$

$w = 96.03 \ rad/s$

The propagation constant k is mathematically represented as

$k = \frac{2 \pi}{\lambda}$

Substituting values

$k = \frac{2 * 3.142}{0. 540}$

$k =11.64 m^{-1}$

Substituting values into the equation for mechanical waves

$y(1.51 , 0.150) = (5.50*10^{-2} ) cos ((11.64 * 1.151 ) - (96.03 * 0.150))$

$y(1.51 , 0.150) = 0.055 m$
