5m/s because all you have to do is add 3 and 8
Answer:
Major term is 'things that provide intense gravity'
Minor term is 'extremely dense objects'
Middle term is 'neutron stars'
Explanation:
- Major term is given by the predicate part of the conclusion
- Minor term is given by the subject part of sentence in conclusion
- Middle term is given by the subject part and not the conclusion
For this problem, we use the conservation of momentum as a solution. Since momentum is mass times velocity, then,
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
where
v₁ and v₂ are initial velocities of cart A and B, respectively
v₁' and v₂' are final velocities of cart A and B, respectively
m₁ and m₂ are masses of cart A and B, respectively
(7 kg)(0 m/s) + (3 kg)(0 m/s) = (7 kg)(v₁') + (3 kg)(6 m/s)
Solving for v₁',
v₁' = -2.57 m/s
<em>Therefore, the speed of cart A is at 2.57 m/s at the direction opposite of cart B.</em>
Answer:
<em>The frequency changes by a factor of 0.27.</em>
<em></em>
Explanation:
The frequency of an object with mass m attached to a spring is given as
= 
where
is the frequency
k is the spring constant of the spring
m is the mass of the substance on the spring.
If the mass of the system is increased by 14 means the new frequency becomes
= 
simplifying, we have
= 
= 
if we divide this final frequency by the original frequency, we'll have
==>
÷
==>
x
==> 1/3.742 = <em>0.27</em>
Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra =
Ra =
= 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb =
Rb =
=
units
Adding these two vectors A and B together, magnitude of vector R is
R = 
R =
= <em>10.09 units</em>
