An epidemiologist is a doctor who counteracts mass infections (epidemics, pandemics), organizes the treatment and prevention of the spread of epidemics.
Answer:
If the force remains the same, the acceleration would decrease
Explanation:
According to Newton's second law, the acceleration of an object is given by
where
F is the force applied to the object
m is the mass of the object
As we see from the formula, the acceleration a is inversely proportional to the mass, m. Therefore, if the force F remains constant, this means that if the mass of the skateboarder increases, then the acceleration will decrease.
Answer:
Pretty sure its -4.8%
Explanation:
Others asked this question and got this as an answer.
C. newtons/meter
Explanation:
The unit of spring constant K is newtons/meter.
The spring constant is also known as the stiffness.
F = k e
F is the force
k is the spring constant
e is the extension.
The unit of F is newtons
e is meters
Therefore, k becomes newtons/meter
- Stiffness is the resistance to stretch of a body.

Starting velocity (u)=0
acceleration (a) = 9.8
time (t) = 1.5
final velocity (v) =?
v=at+u
v=9.8(1.5)+0
v=14.7m/s2
