Answer:
The acceleration of the platform is - 1.8 m/s²
Explanation:
The net force on a body causes that body to accelerate in the direction of the resultant force applied.
Setting up the force equilibrium for the configuration:
ma = 800 - mg
100a = 800 - 100×9.8
100a = - 180
100a = - 180
a = - 1.8 m/s²
This indicates that the body is falling downward.
Response/Clarification:
Each of us receives 2 versions of a gene from our parents, with one inherited from the mother and one from the father.
Both our mother and father possess 2 versions of every gene. Therefore, the specific version we inherit is determined randomly, much like the outcome of a coin flip. This applies to both parents.
For instance, if the mother has one variant causing thick ears (A) and another for thin ears (a), she is Aa.
Similarly, the father also has these variants and is Aa as well.
The father can transfer either A or a, while the mother can also transfer either A or a.
As a result, their offspring can be AA, Aa, or aa. An AA genotype results in thick ears, while aa results in thin ears. The Aa genotype produces ears of intermediate thickness, akin to bunny B. This demonstrates the concept of incomplete dominance
Answer:
(A) = 3.57 m
Explanation:
According to the question, the information provided is:
diameter (d) = 3.2 m
mass (m) = 42 kg
angular speed (ω) = 4.27 rad/s
Using the conservation of energy principle, we have
mgh = 0.5 mv² + 0.5Iω²...equation 1
where
Inertia (I) = 0.5mr²
ω = v/r
Revising equation 1, it turns into
mgh = 0.5 mv² + 0.5(0.5mr²)(v/r)²
resulting in gh = 0.5 v² + 0.5(0.5)v²
This simplifies to 4gh = 2v² + v²
thus h = 3v² ÷ 4g... equation 2
Given ω = v/r, we find v = ωr = 4.27 × (3.2 ÷ 2)
which yields v = 6.8 m/s
Next, substituting the value of v into equation 2 gives us
h = 3v² ÷ 4g
h = 3 × (6.8)² ÷ (4 × 9.8)
h = 3.57 m
