Answer:
the spring constant is -89.2857 n/m
Explanation:
The computation of the spring constant is shown below:
As we know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
F = 25 N
And, x = 0.280m
So, the spring constant would 2
= 25N ÷ 0.280 m
= -89.2857 n/m
Hence the spring constant is -89.2857 n/m
Answer:
<em>The specific heat capacity of something is simply the amount of heat energy required to raise 1g of that substance or object by 1°C.</em>
<em>The specific heat capacity of something is simply the amount of heat energy required to raise 1g of that substance or object by 1°C.It is given by the formula Q = mcΔT, where Q is the energy transferred (J), m is the mass of the substance (kg), c is the specific heat capacity, and ΔT is the temperature change (°C).</em>
Answer:
Nicolaus Copernicus
Explanation:
In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.
