Answer: Migration and hibernation
Explanation: look it up ;)
Answer:
list of spring in order of increasing spring constant is given by,
W, Y, X, Z
Explanation:
Spring W:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 20 / 0.5
k = 40 N/m
Spring X:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 60 / 0.3
k = 200 N/m
Spring Y:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 40 / 0.4
k = 100 N/m
Spring Z:
Magnitude of Force applied on the spring is given by,
F = k x
Where, F = force applied
k = spring constant
x displacement
k = F/x
k = 50 / 0.1
k = 500 N/m
Thus, list of spring in order of increasing spring constant is given by,
W, Y, X, Z
Answer:
ball hit the ground from her feet is 1.83 m far away
Explanation:
given data
speed = 5.3 m/s
angle = 12°
height = 1 m
to find out
how far from her feet ball hit ground
solution
we consider here x is horizontal component and y is vertical component
so in vertical
velocity will be = v sin12
vertical speed u = 5.3 sin 12 = 1.1 m/s downward
and
in horizontal , velocity we know v = 5.3 m/s
so from motion of equation
s = ut + 0.5×a×t²
s is distance t is time a is 9.8
put all value
1 = 1.1 ( t) + 0.5×9.8×t²
solve it we get t
t = 0.353 s
and
horizontal distance is = vcos12 × t
so horizontal distance = 5.3×cos12 × ( 0.353)
horizontal distance = 1.83 m
so ball hit the ground from her feet is 1.83 m far away
This measure of the total amount of matter an object contains is called mass. The unit used for mass is the kilogram or kg for short.
I hope this helps!
