position of the peg is given by the equation

now the rate of change in position is given as




given that


now we have

<em>so its speed will be 3.76 m/s in magnitude</em>
Answer:
1.59 g/mL
Explanation:
Mass of CCl₄ = mass of flask and CCl₄ − mass of empty flask
m = 703.55 g − 345.8 g
m = 357.75 g
Density = mass / volume
d = 357.75 g / 225 mL
d = 1.59 g/mL
Mechanical or Electromagnetic
Answer:
Inverse Square Law Newton proposed the Inverse Square Law. The effect of gravity (and also on forces such as sunlight) works like this. If say we have a half-mass Earth, it would produce a gravity of not half but a quarter (the square of 2).
