Answer:
1s2,2s2,2p6 or (He) 2s2 2p6
Because the Earth rotates through two tidal<span> “bulges” every lunar day, coastal areas experience<em> two </em></span><em>high</em><span><em> and two low </em></span><em>tides</em><span><em> every 24 hours and 50 minutes</em>.
</span>High tides occur<span> 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from </span>high<span> to low, or from low to </span>high<span>.
I hope this helped!! Have an amazing day :))</span>
Answer:
1. Yes, if the elephant is standing still.
2. impulse acting on it.
Explanation:
Momentum is the product of mass and velocity. A change in momentum occurs when any of the quantities change. A change in momentum is equal to impulse acting on it. A change in momentum per unite time generates force.
P = m v
ΔP = Δm v or mΔv
F = ΔP /Δt
Impulse, F Δt = ΔP.
An ant has negligible mass in comparison to an elephant. Thus, an ant can have more momentum only when the elephant is standing still. Then, the momentum of the elephant would be zero as it would have zero velocity. and a moving ant would have more Momentum.
The change in momentum of an object is impulse acting on it.
Impulse, F Δt = ΔP.
<span>The trajectory (parabola) for a "particle" of water follows from:
h(t) = v(0) sin(angle) t - 1/2 g t^2
x(t) = v(0) cos(angle) t
From the second equation t = x / (v(0) cos(angle) )
and substitution in the first to eliminate t gives the parabola h(x):
h(x) = x tan(angle) - (g/(2v(0)^2 cos(angle)^2) x^2
h(x) = 0 is solved by x=0 (where the trajectory starts) and at
x = 2 v(0)^2 tan(angle) cos^2(angle) / g
x = 2 v(0)^2 sin(angle) cos(angle) / g
x = v(0)^2 sin(2 angle) / g [[ using sin(2 ) = 2 sin(s) cos(s) ]]
For the first question (the 2.0m distance question) you have therefore to solve for angle the equation
2.0= 2*(6.5)^2 sin(2 angle) / 9.81
sin(2 angle) = 0.23
angle = 1/2 * arcsin(0.23) = 6.65 degrees
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
Temperature difference in kelvin =7K
Temperature difference in Fahrenheit degree = 12.6°F
Explanation:
Temperature difference = 7°C
273 is added to the Celsius value to convert to kelvin temperature.However if 273 is added to both the initial and final values of the Celsius temperature values, then the difference still stays the same. Hence the difference in kelvin is 7K.
To convert the temperature difference to Fahrenheit we simply multiply 1.8
=7*1.8 = 12.6°F
