Answer:
See below
Explanation:
29 mile/hr * 5280 f/mile / 3600 s/hr = 42.53 ft/ sec
42.53 ft / sec / 12 feet = 3.54 cycles / sec = 3.54 Hz
for frequency I suppose....where is the referred to figure?
Answer:
- The x-component of the velocity of the third particle is
- The y-component of the velocity of the third particle is
- The increase in kinetic energy is
Explanation:
We can take conservation of linear momentum to find the velocities:
The initial momentum of the nucleus will be:
as is at rest.
After the decay, the first particle has a momentum
the second one has a momentum
By conservation of linear momentum we have:
for the third particle, we know that mass is conserved:
The velocity will be:
The kinetic energy is given by
And, as the initial kinetic energy is zero, this must be the increase in energy.
Hi there!
The maximum deformation of the bumper will occur when the car is temporarily at rest after the collision. We can use the work-energy theorem to solve.
Initially, we only have kinetic energy:
KE = Kinetic Energy (J)
m = mass (1060 kg)
v = velocity (14.6 m/s)
Once the car is at rest and the bumper is deformed to the maximum, we only have spring-potential energy:
k = Spring Constant (1.14 × 10⁷ N/m)
x = compressed distance of bumper (? m)
Since energy is conserved:
We can simplify and solve for 'x'.
Plug in the givens and solve.
The equivalent resistance of several resistors connected in series is
the sum of their individual values.
Four 75-ohm resistors connected in series are electrically equivalent
to a single resistor of 300 ohms.
The battery voltage doesn't matter. In fact, it doesn't matter whether the
resistors are anywhere near a battery or not. They could just as well still
be in the little Radio Shack envelope on the top shelf of the storage room.
If they're connected in series, then they're still electrically equivalent to a
single 300-ohm resistor.
Answer:c
Explanation:
When an object is performing simple harmonic motion then time period is given by measuring the time period take by object to return its initial position.
Thus we can say that it also valid for maximum position thus period is the correct is answer for this problem.
Time Period of oscillation for spring mass system is
