Density: 1.9 g/cm3
density = mass/volume
d = 5.7/3
d = 1.9
Answer:
Magnitude of Force : 0.8 N
Explanation:
We know that the velocity of this particle changes from 15ms⁻¹, or in other words 15m / s, to the respective velocity 25m / s over the course of 2.5 seconds. Given this information we can determine the acceleration of the particle,
a = v₁ - v₂ / t = 25 - 15 / 2.5 = 10 / 2.5 = 4m / s²
Knowing the acceleration we can calculate the magnitude of the force using the formula f = ma - Newton's second law of motion,
f = m a = 200g 4m / s² = 800 g m / s²
Remember however that Newtons are in the standard units kg m / s². Therefore we have to convert 800 g to kg to receive our solution,
800 g = 800 / 1000 kg = 0.8 kg,
Magnitude of Force = 0.8 N ; Solution = Option B
Answer:
14.56 N
Explanation:
According to Newton's second law of motion,
The force acting on a body is equal to the product of its mass and acceleration acting on it.
Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.
Here, acceleration due to gravity on planet A is m/s² and mass of an object on it is kg.
So, weight of an object, , on planet A is given as,
