Answer:
C. Sleep Apnea
Explanation:
Sleep Apnea is when someone who snores and stops breathing while sleeping
The weight of an object is given by:
where
F is the weight
m is the mass of the object
is the gravitational acceleration
The piece of ham in this problem has a mass of
m=630 g = 0.63 kg
therefore its weight is
Answer:
Explanation:
Coefficients of Friction
Objects in physical contact produce friction which usually manifests as thermal energy being dissipated in the surface where the objects are interacting. It's usually harder to start to move an object from rest, that keeps moving it at a constant speed on the same surface. That is why there are two different coefficients of friction: the static and the dynamic. As mentioned, the static coefficient is greater than the dynamic coefficient . The car is already moving and is attempting to stop. The coefficient of friction is defined as
Where Fr is the force of friction and N is the normal or the force the road pushes back up on the car. With the given data, we have
The coefficient of friction is dimensionless (doesn't have any units)
Answer:
<h2>1320 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 600 × 2.2
We have the final answer as
<h3>1320 J</h3>
