Density = (mass) / (volume)
= (50.4) / (57.9) = 0.87 gm/cm³
Since the density is less than 1.0, the paraffin floats in water.
Since it's so close to 1.0 on the low side, the paraffin floats
with most of it under the water line.
Answer:
A jet plane flying straight and at level at constant speed
Explanation:
The<em> inertial frame </em>of reference is a frame of reference in which all <em>Newton law is valid</em> ie Newton second law of motion and therefore newton first law of motion holds good. <em>The frame of reference does not accelerate.</em>
All the object that is in the frame of reference are at rest or moving with constant rectilinear motion with constant velocity unless acted upon by any force.
Answer:
True
Explanation:
i searched it up and well this thing is making me do it up till 20 characters long so yea
The effective temperature of a star is relative to the
fourth root of the luminosity and is contrariwise proportional to the square
root of the radius.
L = k R² T⁴
If the radius remains continuous, while the luminosity doubles, the temperature
must increase by a factor of the fourth root of two.
If L → 2L, then T → 1.189207115 T
So the answer is approximately 1.19 times.
