Answer:
1) mass of the objects
2) distance between their centers
Answer:
1. The Speed is 390
2. The Frequency is 425 Hz
3. The Wavelength is 1.3
Explanation:
1. To find the speed of a wave you have to do the formula of speed.
Speed = Wavelength x Wave Frequency.
Speed = 1.5 * 260
= 390
2.
Formula
F= 
F = 340 / 0.8
= 425
3.
Formula
Wavelength = speed / frequency
Wavelength = 440 / 344 (rounded to nearest tenth if necessary)
= 1.3

Gravity holds everything in the galaxy together.
Answer:
<em>600N(downwards)</em>
Explanations
<em>600N(downwards)</em>
Mas of the person = 60kg
Acceleration due to gravity = -10m/s²
To get the earths pull on the person, we will use the Newton second law of motion;
Force = mass * acceleration;
Force = 60 * -10
Force- -600N
<em>Hence the earth gravitational pull on the person is 600N(downwards). It is downwards due to the negative sign.</em>
