worty [1.4K]

Answer:

b. 0.75 mm

Explanation:

The distance between antinodes d is half the wavelength $\lambda$ . We can obtain the wavelength with the formula $v=\lambda f$ , where f is the frequency given ( $f=1MHz=1\times10^6Hz$ ) and v is the speed of sound in body tissues (v=1540m/s), so putting all together we have:

$d=\frac{\lambda}{2}=\frac{v}{2f}=\frac{1540m/s}{2(1\times10^6Hz)}=0.00077m=0.77mm$

which is very close to the 0.75mm option.

1)If I'm on an elevator that breaks loose and plummets down the shaft, can I avoid harm by jumping at the last second?

umka2103 [35]

Answer and Explanation:

1) If you were to jump at the last second, you would decrease the impact velocity by 7 mph. This is because most humans have a maximum jump velocity of 7 mph. You may still get hurt, but the damage would be significantly less than if you were to not jump.

2) Bathroom mats are made of fabrics, and fabrics absorb the moisture in the air. If you were to take a shower at any temperature, the fabric will soak up the moisture in the air, so when you touch it, it doesn't feel cold.

The tile floor, however, isn't able to store the moisture into itself. The temperature of the tile will be less than the temperature of your feet.
