Answer:

option 4

Explanation:

Light's velocity in air ( 3 × 10^8 m/s ) is much greater than sound's velocity in air ( 343 m/s )

Hence due to difference in velocities , during lightning light is seen first & sound is heard later

When driving a Toyota avensis car along a straight road for 16.5km at
Vitek1552 [10]

The average velocity of the whole journey will be total distance covered divided by the total time. It will be approximately equal to 8 m/s. The right answer is option B

<h2>VELOCITY</h2>

Velocity is the distance travelled in a specific direction. While the average velocity of the whole journey will be total distance covered divided by the total time

When driving a Toyota avensis car along a straight road for 16.5km at

50km/h,

The velocity = 50 km/h

Distance = 16.5 km

Use the speed formula to calculate time.

Speed = distance / time

Time = distance / speed

Time = 16.5 / 50

Time = 0.33 s

If over the next 20min, you walked another 2.5km further along the road for a petrol station, Then,

average velocity = Total distance covered divided by total time taken.

Where

The time t = 20/60 = 0.333 h

Total time = 0.33 + 0.3333

Total time = 0.6633333

Total distance = 16.5 + 2.5

Total distance = 19 km

Average velocity = 19 / 0.66333

Average Velocity = 28.64 km/h

Now convert Km/h to m/s

(28.6432 x 1000) / 3600

286432 / 3600

7.956m/s

Therefore, the average velocity of the whole journey from beginning of the drive to the arrival at the filling station will be approximately 8 m/s

Please I need help........
LenKa [72]

Answer:

7.46 J/kg/K

Explanation:

The heat absorbed or lost is:

q = mCΔT

where m is the mass, C is the heat capacity, and ΔT is the change in temperature.

Given q = 15.0 J, m = 0.201 kg, and ΔT = 10.0 °C:

15.0 J = (0.201 kg) C (10.0 °C)

C = 7.46 J/kg/°C

Which is the same as 7.46 J/kg/K.
