<span>Learning by assimilation is so effective for it involves a
concise and logical approach. Most people who require clear understanding and explanation
of ideas, information and abstract concepts must use this approach of learning.
The reason is that, they are more attracted to logically sound theories rather than more
focus on people approach and based on practical value. </span>
In assimilating learning, people prefer readings, listening to
lectures, exploring analytical models, and having time to think things through
on their own. With this, all the important concept and data is clearly
inculcated and stored in mind.
Answer:
= 1.132 A
Explanation:
Given that:
A 120-V rms voltage at 60.0 Hz which applied across an inductor, capacitor and a 100- resistor in series.
If the maximum value of the current in this circuit
= 1.60 A
what is the rms value of the current in this circuit i.e the
= ????
The relation between
and
can be expressed by the formula:
= 
1.60 = 1.414 * 
= 
= 1.132 A
Thus, the value of the current this circuit = 1.132 A
The difference in the force exerted by the ground during a race between these two species is 259.25
<h3>What is force?</h3>
Forces are influences that can change the movement of an object. A force can change the velocity of an object with mass, i.e. accelerate it. Forces can also be described intuitively by pushing or pulling. A force has both magnitude and direction and is a vector quantity.
Force exerted by the lion:
Normal force = mg
170 = m × 9.8
m = 17.34 kg
Forward force = ma
= 17.34 × 10.0
= 173.4 N
Total force = Normal force + Forward force
Total force = 170 + 173.4
= 343.4 N
Force exerted by the man:
Normal force = mg
75 = m × 9.8
m = 7.65 kg
Forward force = ma
= 7.65 × 10.0
= 76.5 N
Total force = Normal force + Forward force
Total force = 7.65 + 76.5
= 84.15 N
The difference in the forces exerted by these species is:
343.4 N - 76.5 N = 259.25 N

Answer:
a) 230 Km b) 76.7 km/h c) Please see below
Explanation:
a) If we can neglect the time while the driver accelerated, the movement can be divided in two parts, each of them at a constant speed:

⇒ 
b) The average x component of velocity, can be calculated applying the definition of average velocity, as follows:

If we choose t₀ = 0 and x₀ = 0, replacing xf and t by the values we have already found, we can find vavg,x as follows:

c) The found value of avg,x is not the same as the arithmetic average of the initial and final values of vx (70 Km/h) due to the time traveled at both velocities was not the same.
If the driver had droven half of the time (1.5 h) at 50 km/h and the other half at 90 km/h, total displacement would have been as follows:

Applying the definition of average velocity once more:

which is the same as the arithmetic average of the initial and final values of vₓ.
Answer:
Rod 1 has greater initial angular acceleration; The initial angular acceleration for rod 1 is greater than for rod 2.
Explanation:
For the rod 1 the angular acceleration is
Similarly, for rod 2

Now, the moment of inertia for rod 1 is
,
and the torque acting on it is (about the center of mass)

therefore, the angular acceleration of rod 1 is


Now, for rod 2 the moment of inertia is


and the torque acting is (about the center of mass)


therefore, the angular acceleration
is


We see here that

therefore

In other words , the initial angular acceleration for rod 1 is greater than for rod 2.
