32. Which statement best describes the difference between strong nuclear forces and weak nuclear forces? (2 points)
• Weak nuclear forces are involved when certain types of atoms break down. Strong nuclear forces are
responsible for holding atoms' nucleus together.
• Weak nuclear forces hold bonds between atoms together. Strong nuclear forces hold together the nucleus of an atom.
• Strong nuclear bonds prevent atoms from falling apart. Weak nuclear bonds prevent compounds from falling apart.
• Strong nuclear forces are involved in breaking electrons from their shells. Weak nuclear forces hold protons in the nucleus. in

Answer:

TWO

Explanation:

Answer:

1.25 s

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 25 m/s

Angle of projection (θ) = 30°

Acceleration due to gravity (g) = 10 m/s²

Time (t) to reach highest point =?

The time taken for the particle to reach the highest point can be obtained as follow:

t = uSineθ / g

t = 25 × Sine 30 / 10

t = 25 × 0.5 / 10

t = 12.5 / 10

t = 1.25 s

Thus, it will take the particle 1.25 s to reach the highest point.

A wave is an energetic disturbance in a medium that doesn't include any net particle motion. The velocity of the waves in the string of 0.620 m long which oscillates at 234 Hz is 72.54 m/s.

The distance between two successive wave crests or troughs is referred to as the wavelength. It is estimated in the direction of the wave. Typically, the wavelength is denoted by the symbol λ. The metre is its SI unit.

The relationship between wavelength and frequency is inverse. A wave's frequency decreases as its wavelength increases.

v = fλ

Here length, L = 2λ

λ = L / 2 = 0.620 / 2 = 0.31 m

v = 234 × 0.31 = 72.54 m/s

Answer:

[tex]\alpha =1.5\ rad/s^2[/tex]

Explanation:

Given that,

Initial angular velocity, [tex]\omega_i=0[/tex]

Final angular speed, [tex]\omega_f=6\ rad/s[/tex]

Angular displacement, [tex]\theta=12\ rad[/tex]

We need to find the angular acceleration of the tire. We can find it using the third equation of rotational kinematics. So,

[tex]\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{6^2-0^2}{2\times 12}\\\\\alpha =1.5\ rad/s^2[/tex]

So, the angular acceleration of the tire is equal to [tex]1.5\ rad/s^2[/tex].

Answer:

As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second

Answer:

v = 1.098 m/s

Explanation:

Given that,

A person walks 750m due north then 250 m due east of the entire walk takes 12 min.

We need to find the average velocity of the person.

Displacement,

[tex]d=\sqrt{750^2+250^2} \\\\d=790.56\ m[/tex]

Average velocity = displacement/time

[tex]v=\dfrac{790.56\ m}{12\times 60\ s}\\\\v=1.098\ m/s[/tex]

So, the average velocity of the person is 1.098 m/s.

Answer:

Distance: 21km

Displacement: ~16.76km

Answer:524 Hz

Explanation:

Approximate frequency, heard in other car, when two car approaches each other, before they cross each other is 524 Hz.

Frequency of wave is the number of waves, which is passed thorough a particular point at a unit time.

For the two cars approaching each other the Doppler formula to find the frequency of second car is given as,

[tex]f_2=\dfrac{V_s+V_2}{V_s-V_1}f_1[/tex]

Here, [tex]V_s[/tex] is the speed of the sound.

Two cars approach each other from opposite directions.The velocity of car one is 54 km/h and the velocity of the car two is also 54 km/h.

Convert the unit of velocity of the car as,

[tex]\rm 54km/s=54\times\dfrac{5}{18}m/s\\\rm 54km/s=15m/s[/tex]

As we know that the speed of the sound is 340 m/s and one of the cars emits a note of frequency 480 Hz.

Thus, putting the values in the above formula to find out the frequency heard in the other car before they cross each other as,

[tex]f_2=\dfrac{340+15}{340-15}480\\f_2=524.3\rm Hz[/tex]

The approximate frequency heard in the other car before they cross each other is 524 Hz.
