Answer:

Option C

Explanation:

Option C

Vibrational motion is best expressed among the given is a cello playing music at the concert. A cello is a music instrument it is primarily a string instrument. All its four strings are tuned in perfect fifths from low to high. All other option seem out of context.  A cello is primarily an Itallian instrument its players are called Cellist.

a train engineer drives a train 235 km north along a straight track . then he drives the train back south 126 km . finally , he
yuradex [85]

let here North direction is along +Y and South direction is along -Y

similarly East direction is towards +X and west direction is towards -X

now it is given that

first it moves 235 km north

d_1 = 235 \hat j

then it moves back 126 km south

d_2 = - 126 \hat j

then again he moves north

d_3 = 45 \hat j

now the total displacement is given as

d = d_1 + d_2 + d_3

d = 235 - 126 + 45 = 154 km

so final displacement of train is 154 km North

Which is an example of radioactivity that occurs when a neutron is converted to a proton and an electron is emitted from the nuc
aleksandr82 [10.1K]

Answer:

Beta minus decay

Explanation:

Beta decay is due to a weak nuclear interaction, it takes place in the atomic nucleus and occurs when a neutron is converted to a proton, or a proton into a neutron. When a neutron is converted to a proton an electron and an electronic antineutrino are emitted from the nucleus, this is called beta minus decay.

A box of mass 26 kg is initially at rest on a flat floor. The coefficient of kinetic friction between the box and the floor is 0
Kazeer [188]

Answer:

\Delta K = 52J

Explanation:

The change in kinetic energy will be simply the difference between the final and initial kinetic energies: \Delta K=K_f-K_i

We know that the formula for the kinetic energy for an object is:

K=\frac{mv^2}{2}

where <em>m </em>is the mass of the object and <em>v</em> its velocity.

For our case then we have:

\Delta K = K_f-K_i=\frac{mv_f^2}{2}-\frac{mv_i^2}{2}=\frac{m(v_f^2-v_i^2)}{2}

Which for our values is:

\Delta K = \frac{m(v_f^2-v_i^2)}{2} = \frac{(26Kg)((2m/s)^2-(0m/s)^2)}{2} = 52J
