Answer:
It will sink
Explanation:
An object in the water can float only if its density is lower than the density of the water.
In fact, for an object completely immersed in water, there are two forces acting on it:
- Its weight, 
, downward, where 
is the density of the object, V its volume and g the gravitational acceleration
- The buoyant force, 
, upwards, there 
is the density of the water
We see that when the density of an object is larger than the density of the water, 
, the weight is greater than the buoyant force, 
, so the object sinks.
In this case, the rock has a density of 1.73 g/cm3, while water has a density of 1.0 g/cm^3, so the rock will sink.
It can be calculated using Boyle's Law. A.
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
Answer:
a) Fc = 4.15 N, Fi = 435.65 N, (F1)a = 640 N, and F2 = 239.6 N,
b) Ha = 1863.75 N, nfs = 1 , length = 11.8 mm
Explanation:
Given that:
γ= 9.5 kN/m³ = 9500N/m3
b = 6 inches = 0.1524 m
t = 0.0013 mm
d = 2 inches = 0.0508 m
n = 1750 rpm
L = 9 ft = 2.7432 m
Ks = 1.25
g = 9.81 m/s²
a)
b)
dip = 
Answer:
90.77%
its capacity utilization rate for the month is 90.77%
Explanation:
The capacity utilisation rate can be expressed mathematically as;
Capacity utilisation rate = capacity used/Best operating level × 100%
Given;
Total Number of production time = 205hours
Production output/capacity used = 21400 units
Best operation rate = 115units/hour
Best operation output for the month of July( at best operation level )
=115units/hour × 205 hours = 23575 units
Capacity utilisation rate = 21400/23575 × 100%
= 90.77%
