Answer: 100 km

Explanation:

Given that:

Speed of bicyclist = 40.0 km/hr

Time taken = 2.5 hrs

Distance traveled = ?

Since speed is obtained by dividing the distance travelled by the time taken,

Speed = distance / time

40.0 km/hr = distance / 2.5 hours

Distance = 40.0 km/hr x 2.5 hours

Distance = 100 km

Thus, the bicyclist travelled as far as 100 kilometres

100 km. 40x2.5=100. Hope this helps

According to the principle of conservation of momentum, A. the amount of momentum of all the objects in the universe is constant
anygoal [31]

Answer:

D. in a closed system, an object's momentum before a collision will equal its momentum after the collision.

Explanation:

As we know by newton's II law we have

F = \frac{\Delta P}{\Delta t}

so we will have

F = net force on the system

\Delta P = change in momentum

so we can say if the momentum is conserved or the initial momentum of the system will be equal to the final momentum of the system

then we will say that

\Delta P = 0

so net force on the system must be ZERO

so in such type of questions the system must be isolated and there is no external force on it

so correct answer will be

D. in a closed system, an object's momentum before a collision will equal its momentum after the collision.

A material kept at high temperature is seen to emit photons with energies of 0.3 eV, 0.5 eV, 0.8 eV, 2.0 eV, 2.5 eV, and 2.8 eV.
sukhopar [10]

Answer:

0.3 eV, 0.5eV,, 8 eV, 2.0eV, 2.50 eV, 2.8 eV

Explanation:

In a given material the emission and absorption spectra are equivalent, for which the emission spectrum observed at high temperature for the material corresponds to the transition between the energy states of the material, the process is that the electrons exist from the ground state until an excited state and after a short period of time or these electrons relax emitting photons.

In the absorption process, the material is at low temperature, ideally at A = 0K, whereby all states are in the ground state and all excited states are empty. therefore it can absorb the beam energy for each transition given from the ground state to each excited edtado.

Consequently, the lines above the absorption oscillate lines coincide with the lines of emotion, this we see lines oscillate at 0.3 eV, 0.5eV,, 8 eV, 2.0eV, 2.50 eV, 2.8 eV
