A sand core used to form the internal surfaces of a steel casting experiences a buoyancy force of 225 n. the volume of the mold

pashok25 [27]

Newton’s second law gives us the relationship of force F, mass m and acceleration a. The formula is given as:

F = m a --> 1

However we also know that the relationship of mass m, density ρ, and volume V is:

m = V ρ --> 2

Therefore substituting equation 2 to equation 1:

F = ρ V a = ρ V g

where a is acceleration due to gravity, ρ is density of water and V is the volume of the casting, therefore:

F = (1x10^-3 kg/cm^3) (4840 cm^3) (9.8 m/s^2)

F = 47.432 kg m/s^2

F = 47.432 N

Going back to equation 1:

47.432 N = m (9.8 m/s^2)

m = 4.84 kg

Hence the weight of the final casting is 4.84 kg

You see a lightning bolt flash in the distant sky. You hear the corresponding thunder 6.8 seconds later. If the temperature is 2

Anna35 [415]

Answer:

$Distance = 2.4\ km$

Explanation:

Given

$Time (t) = 6.8s$

$Temperature = 28C$

Required

Determine the distance at which the lighting struck

First, we need to determine the speed at which the lighting struck because the peed of sound varies with temperature.

At about 28C, the speed of sound is 346m/s

So, we have the following:

$Speed = 346m/s$

$Time = 6.8s$

Distance is calculated as thus:

$Distance = Speed * Time$

$Distance = 346m/s * 6.8s$

$Distance = 2352.8$

Divide by 1000 to get distance equivalent in kilometers

$Distance = \frac{2352.8km}{1000}$

$Distance = 2.3528km$

$Distance = 2.4\ km$ ---- Approximated
