Acceleration=force/mass=28/(10+4)=2m/s^2
force10kg=ma=10*2
force4kg=ma=(10*2)=20
the4 kg is pushing against the 10kg block
vf=vi+at
-10=20*28/14 * t
t=30/2=15sec
i hope this can help you.
Explanation:
charles law V1/T1 =V2/T2
560 x 673 =V2/973
376880 = V2/973
V2 = 376880 x 973 = 366704240mL
Explanation:
Weak nuclear force:
The interaction between the subatomic particles is called weak nuclear force.
The weak nuclear force is one of the four fundamental forces.
The weak nuclear force is effective at very short distance.
The range and relative strength of weak nuclear force is 10⁻¹⁸ m and 10²⁵ with respect to gravitational force respectively
Deuterium is formed due to the fusion of protons and neutrons under the action the weak force.
Example : Beta decay
Electromagnetic force:
The interaction between the charged particles is called electromagnetic force.
The electromagnetic force is one of the four fundamental forces.
The electromagnetic force is effective at long range distance.
The range and relative strength of electromagnetic force is infinity and 10³⁶ with respect to gravitational force respectively
Example : light
Answer:
primary advantage of composite material are high strength, low weight, corrosion resistance
Explanation:
The primary advantage of composite material is
1) high strength - they are stronger in strength than commanly used material like steel and aluminium.
2)low weight - lighter than most of the material like woods and others metals
3) corrosion resistance - it resist extreme condition of weather and can be good place where handling of chemicals takes place.
