Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
"some elements have only one stable isotope"
Explanation:
there ya go! Pls give me brainliest!
Well, Bianca, I'll tell ya. You really haven't told us enough to completely define exactly what's going on here. In fact, now that I look at it carefully, you've told us nothing at all ... only asked a question based on zero given information.
IF you're talking about an object like a baseball or a rock or another projectile of some kind, and IF the object has no jet engines on it, and IF it has been tossed, launched, thrown, or otherwise sent on its way to somewhere other than the place it left from, and IF it's OK to ignore the effects of air resistance, then ...
-- the only force acting on the object is the force of gravity
-- gravity only points down
-- gravity has no effect on horizontal velocity
-- horizontal velocity is <em>constant</em>, and <em>doesn't change </em>as time goes on.
But IF any of these things is different, then you can forget everything I said. I'm just guessing.
Answer:
The final temperature is 21.531°c
Explanation:
Heat gained by the water = heat lost by the metal
Heat gained = (m)(c)(∆tita)
Where m = mass
C = specific heat capacity
∆tita = temperature change
X = equilibrium temperature
So ....
Heat gained by water
= 175*4.185*(x-20)
= 732.2x - 14644
Heat lost by metal
= 44.5*0.321*(100-x)
=1428.45 -14.2845x
So....
1428.45 - 14.2845x = 732.2x - 14644
1428.45+14644= 732.2x + 14.2845x
16072.45= 746.4845x
16072.45/746.4845= x
21.531 = x
The final temperature is 21.531°c
The speed of the wavelength on this string 322.4 m/s.
Given,
Half wavelength = 0.65m,
So, Wavelength = 2*.65=1.3m, frequency=248Hz
Speed=wavelength*frequency=1.3*248=322.4 m/s.
<h3 /><h3>Wavelength</h3>
The wavelength, or spatial period, of a periodic wave in physics refers to the length over which the wave's structure repeats. It is the separation between neighbouring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.
The lowest frequency of a guitar string with a length 0. 65 m is 248 hz. what is the speed of the wave on this string?

Hello,
Let's consider the temperature in any scale be "<em>x</em>".
Then,
• Temperature in Celsius = <em>x</em><em> </em>°C
• Temperature in Kelvin scale = <em>x</em><em> </em>K
