Answer:
How Urgent are we talking?
Explanation:
Answer: have "cis C=C double bonds" and "liquid" at room temperature.
Explanation:
The unsaturated fatty acids have one or more C=C double bonds in the cis formation. Thus, this results in the molecules not been as stable as the saturated fats. They have weaker intermolecular bonds thus resulting in lower melting point . The consequently results in it being liquid at room temperature.
The answer would probably be B.
Answer:
No, the pendulum's period of oscillation does not depend on initial angular displacement.
Explanation:
Given that,
For small angle, the pendulum's period of oscillation depend on initial angular displacement from equilibrium.
We know that,
The time period of pendulum is defined as

Where, l = length of pendulum
g = acceleration due to gravity
So, The time period of pendulum depends on the length of pendulum and acceleration due to gravity.
It does not depend on the initial angular displacement.
Hence, No, the pendulum's period of oscillation does not depend on initial angular displacement.
Answer:
0.33m/s²
Explanation:
Given parameters:
Initial velocity = 19.9m/s
Final velocity = 4.4m/s
Time = 47.6s
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression below:
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Acceleration =
Acceleration = -0.33m/s²
This is a deceleration
