Answer:
0.09 m/s to the right
Explanation:
The principle of conservation of linear momentum states that in a system of colliding objects, the total momentum before collision is equal to the total momentum after collision, provided there is no external force.
The total momentum, in this question, is the sum of the momentum of the the two marbles. We assume velocity to the right is positive while to the left is negative. Thus, total initial momentum is
After collision, the first marble goes left. Let the velocity of the other marble be v. Then we have
Equating both momenta,
Hence, the larger goes right with a velocity of 0.09 m/s (since it has a positive sign).
<h2>
Answer:</h2>
Shown in the explanation
<h2>
Explanation:</h2>
Position vector of a particle at a given instant is given by:
On the other hand, the average velocity is the change in the particle’s position vector divided by time interval:
So we have:
Finally, the average velocity is:
Answer:
The specific heat capacity is q_{L}=126.12kJ/kg
The efficiency of the temperature is n_{TH}=0.67
Explanation:
The p-v diagram illustration is in the attachment
T_{H} means high temperature
T_{L} means low temperature
The energy equation :
= R* 
in(
/
)
The specific heat capacity:
=q_{h}*(T_{L}/T_{H})
q_{L}=378.36 * (400/1200)
q_{L}=378.36 * 0.333
q_{L}=126.12kJ/kg
The efficiency of the temperature will be:
=1 - (
/
)
n_{TH}=1-(400/1200)
n_{TH}=1-0.333
n_{TH}=0.67
The answer is B. metalloids
(boron, silicon, germanium, arsenic, antimony, tellurium, astatine, and polonium)
The cat fell 1.0 m from the ground.
Using the formula
Here, 
Solving for t, the time it spent in the air is
The cat does not accelerate along the horizontal, so it has constant horizontal velocity. Since it strikes the floor 2.2 m from the table, then
