Answer:
The final velocity of the object is 330 m/s.
Explanation:
To solve this problem, we first must find the acceleration of the object. We can do this using Newton's Second Law, given by the following equation:
F = ma
If we plug in the values that we are given in the problem, we get:
42 = 7 (a)
To solve for a, we simply divide both sides of the equation by 7.
42/7 = 7a/7
a = 6 m/s^2
Next, we should write out all of the information we have and what we are looking for.
a = 6 m/s^2
v1 = 0 m/s
t = 55 s
v2 = ?
We can use a kinematic equation to solve this problem. We should use:
v2 = v1 + at
If we plug in the values listed above, we should get:
v2 = 0 + (6)(55)
Next, we should solve the problem by performing the multiplication on the right side of the equation.
v2 = 330 m/s
Therefore, the final velocity reached by the object is 330 m/s.
Hope this helps!
If the velocity is constant, then the position/time graph has a constant slope, meaning a straight line.
The slope may be any constant value ... positive, negative, or zero.
-∞ < slope < +∞
Answer:
Gravity
Explanation:
The source of the centripetal force that keeps the mass in a stable circle is gravity.
As the resistance of a circuit increases, the current will decreases.
<h3>What is ohm’s law?</h3>
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
When all physical parameters and temperature are constant,
Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.
This current-voltage connection may be expressed mathematically by Ohm's law as;
V=IR
If the voltage is constant, the resistance of the circuit will be inversely proportional to the current.
Hence,as the resistance of a circuit increases, the current will decreases.
