Answer:
A.Amorphous solid
Explanation:
There are two states used to describe solids in science; these are crystalline and amorphous (non-crystalline) solids.
Crystalline solids are solids whose constituent particles are properly arranged in a 3-dimensional structure in a crystal-like manner. They have a definite melting point and a defined shape and pattern. A common example of a crystalline solid is diamond.
Amorphous or non-crystalline solids are the opposite of the crystalline solids as there constituent particles are disorderly arranged. They do not have a defined melting point as they melt over a range of temperature.
From the above, it can be deduced that candle wax exhibits the properties of amorphous solids. give me brainliest please
Answer:
≈ 20.35 N [newton's of tension]
Explanation:
( (2.9 × 9.8) ÷ cos(35.6°) ) × sin (35.6°) =
( (28.42) ÷ (≈0.813) ) × (≈0.582) =
(≈34.96) × (≈0.582) = 20.3449446.... ≈ 20.35
Answer:
The acceleration of the rattlesnake, a = 126 m/s²
Explanation:
Given,
The initial velocity of the rattlesnake, u = 1.0 m/s
The final velocity of the rattlesnake, v = 20.0 m/s
The time duration to reach the final velocity, t = 0.15 s
The acceleration of a body defined as the rate of change of velocity by time, or simply the difference of final velocity and initial velocity by time.
The formula for acceleration is
a = (v-u)/t m/s²
Substituting the values in the above equation
a = (20 - 1.0 ) / 0.15
= 126 m/s²
Hence, the acceleration of the rattlesnake is, a = 126 m/s²
Answer:
12m/s
Explanation:
Using the equation of motion
v = u + at
Given that
u = 0m/s
a = 2m/s²
time t = 6s
Substitute the given values into the expression
v = 0 + 2(6)
v = 0+12
v = 12m/s
Hence the required velocity is 12m/s
