Answer: The perpendicular force to be used to tighten the bolt is
F=347.8N
Explanation:
Mathematically the torque is expressed as
T=F*L
Where T= torque in Nm
F= force in N
And L = perpendicular distance
Now given
T=63.3Nm
L=18.2cm to meter 18.2/100
0.182m
F=?
Making F the subject of the formula in our equation
F=T/L
F=63.3/0.182
F=347.8N
What is torque?
Torque is the product of force and perpendicular distance of the line of action.
Reflection of lights rays
Answer:
20kph
Explanation:
Since she travels 100kpm in 5 hours and 100 divided by 5 is 20 she would travel 20km in one hour
Explanation:
The aircraft is traveling north at 100 m/s.
The wind blows from the west (towards the east) at 25 m/s.
The two vectors form a right triangle. The magnitude of the resultant velocity can be found with Pythagorean theorem:
v² = vx² + vy²
v² = (25 m/s)² + (100 m/s)²
v = 103 m/s
The direction can be found with trigonometry:
θ = atan(vy / vx)
θ = atan(100 / 25)
θ = 76.0°
The resultant velocity is 103 m/s at 76.0° north of east.
Answer:
The specific heat capacity of molybdenum is
0.2696 joule/gram
Explanation:
Step one
Given that
Mass of molybdenum Mm =237g
Temperature of molybdenum
T1=100°c
Mass of water MW =244g
Temperature of water T2= 10°c
Final temperature T3 =15.3°c
Step two :
We know that the specific heat capacity of water Cw 4.186 joule/gram
But Specific heat capacity of molybdenum Cm?
We know that the quantity of heat transfered can be expressed as
Q=Mm*Cm(T1-T3)+MW*Cw(T2-T3)
since the system attained thermal equilibrium then the expression
Is
=Mm*Cm(T1-T3)=MW*Cw(T3-T2)
Substituting our values into the equation we have
237*Cm(100-15.3)=244*4.186(15.310)
20073.9Cm=5413.3352
Cm=0.2696 joule/gram
Specific heat capacity of molybdenum is 0.2696 joule/gram
