Answer:
The nail penetrates into the frame by 1.875 inches
Explanation:
For an 8d nail, it has a length of 2.5 inches, a diameter of 0.13 inches and a head diameter of 0.28125 inches. 8d nails in buildings are used in attaching studs to wall plate, rafter to top wall plates. It is also used when you need to drive a nail at an angle into a wood member.
Since the depth of an 8d nail is 2.5 inches and the sheathing is nailed on the wood frame, to get how far the point of the nail penetrate into the frame, we subtract the depth of the oriented strand board sheathing from the depth of an 8d nail.
Therefore, how far the point of the nail penetrate into the frame = 2.5 inches - 5/8 inches = (2.5 - 0.625) inches = 1.875 inches.
The nail penetrates into the frame by 1.875 inches
Answer:
The product of mass and velocity is the correct answer
Explanation:
Momentum is defined as mass × velocity
p = mv
The correct answer is whorfianism
Answer:
49.12 °C
Explanation:
= mass of gold sheet = 12 g
= specific heat of gold = 0.129 J/g°C
= initial temperature of gold sheet = 15 °C
= mass of iron sheet = 20 g
= specific heat of iron = 0.449 J/g°C
= initial temperature of iron sheet = 55 °C
= Final equilibrium temperature
Using conservation of heat
Answer:
The period of the resulting oscillatory motion is 0.20 s.
Explanation:
Given that,
Spring constant
We need to calculate the time period
The object is at rest and has no elastic potential but it does has gravitational potential.
If the object falls then the the gravitational potential change in to the elastic potential.
So,
Where,h = distance
k = spring constant
Put the value into the formula
Using formula of time period
Put the value into the formula
Hence, The period of the resulting oscillatory motion is 0.20 s.
