Answer:
The magnitude of acceleration is 3 m/s^2.
Explanation:
The net force along North-South direction is 18-24=-6 N.
The net force along East-West direction is 16-16=0 N
The net magnitude of force is square root of (-6)^2+0^2 which is 6 N.
By Newton's Second law,
Force F=ma
Therefore acceleration a=F/m
a=6/2
a=3 m/s^2

Answer:
Half as large.
Explanation:
Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:
Which clearly shows that the force that the planet exerts on the Moon 2 is half the force it exerts on the Moon 1.

4.5 m
Explanation:
= frequency of the tone = 329.6 Hz
= Time period of the sound wave
we know that, Time period and frequency are related as
= speed of the sound in the air = 341 ms⁻¹
wavelength of the sound is given as
= speed of the sound in the water = 1480 ms⁻¹
wavelength of the sound in water is given as
Just learned this in chemistry. There are no subscripts, therefor each element only has 1 atom. Na has 1, O has 1 and H has one. There are 3 atoms.
