Answer:twice of initial value
Explanation:
Given
spring compresses 
distance for some initial speed
Suppose v is the initial speed and k be the spring constant
Applying conservation of energy
kinetic energy converted into spring Elastic potential energy
When speed doubles
divide 1 and 2
Therefore spring compresses twice the initial value
Melting. Water freezes at 0 degrees celsius or 32 degrees fahrenheit and therefore water freezes at that temperature or ice melts back to its liquid state at those temperatures.
Answer:
C. posotive
I dont have any idea to explain my answer.. all I know is that is the aswer
Answer: The plasma membrane is called a selectively permeable membrane as it permits the movement of only certain molecules in and out of the cells. Not all molecules are free to diffuse. If plasma membrane ruptures or breaks down then molecules of some substances will freely move in and out of the cells.
Answer:
a) d= 13.2cm
b ) vmax =62.23cm/s
c) amax=1172.81cm/s2
Explanation:
Given:
frequency is 3.00Hz,
the amplitude is 3.30cm.
(a)The total distance travelled by the particle during one cycle is.
d = 4A
d= 4×3.30cm
d = 13.2cm
b) The maximum speed of the particle is calculated as using the formula;
vmax = ωA
= 2πfA
= 2π (3.30cm/s)*(3.0cm/s)
=2× 3.147 × 3.30 × 3.0
vmax =62.23cm/s
The maximum speed occur at mean position(x,0) which means it has maximum speed when it passes through the equilibrium position.
(c) The maximum acceleration of the particle is
calculated below;
amax = ω2A
= (2πf)2A
= (2× 3.142×3)^2×3.30
amax=1172.81cm/s2
The particle has maximum acceleration at the turning points.
