Answer:
b.
Explanation:
a. from the spring-mass system which is explicitly describe by hooks law
from
F=-kx
which is in comparison to newtons general law of motion
F=ma
where the displacement x is expressed as
and the acceleration is the second derivative of the displacement
hence final expression after substituting for the acceleration and the displacement is expressed as
b. for k=105N/m and m=3.4kg
we have the angular frequency to be
Answer: Ok um so The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Explanation:
Answer:
Q = 231.6 J
Explanation:
Given that,
Mass, m = 3 g
The temperature rises from 20°C to 220°C.
We know that, the specific heat of copper is, c = 0.386 J/g K
We know that the energy transferred in heating of copper is given by :
So, the required energy is equal to 231.6 J.
O no,O no,O no actualy the point is that I don’t know the answer to the question
ANSWER:
The easiest way to get a fairly accurate measure of your water flow rate is to time yourself filling up a bucket. So for example if you fill up a 10 litre bucket in 1.5 minutes, then your flow rate will be: 10/1.5 = 6.66 Litres per minute.
