Answer:
The distance in -x axis is 39.77 m
Explanation:
Given that,
Distance in +x axis = 24 m
Time = 3.5 sec
Total time = 9.3 sec
Average velocity = 0
We need to calculate the velocity in +x axis
Put the value into the formula
We need to calculate the velocity in -x axis
We need to calculate the distance
Using formula of average velocity
Hence, The distance in -x axis is 39.77 m.
Answer:
a
The time it would take the beef to reach a temperature of 0⁰C is t= 662 sec = 11.93 min
b)
The time it would take to heat the beef to uniform temperature of 80⁰C is
t = 365 sec =5.93 min
c
Efficient absorption of Microwave power is in regions of liquid water . Hence if the food or the microwave irradiation is not uniform, the power will be absorbed non-uniformly, resulting in a non-uniform temperature rise. Defrost region will absorb more energy per unit volume than frozen region.if food is of low thermal conductivity, there will be insufficient time for heat conduction to make the temperature more uniform.Use of low power allows more time for conduction to occur.
Explanation:
The explanation is shown on the first second and third uploaded image
The correct choice is
B) false
as the wave moves from a less dense medium to a denser one, the frequency of the wave does not change. we know that the energy of the wave directly depends on the frequency. Since the frequency of wave does not change while moving from less dense medium to more dense medium, the energy of the wave does not change.
Answer:
water cycle show the continuous movement of water with in the earth and atmosphere

Hope this helps :)
On a velocity - time graph, if the line crosses the x - axis it depicts that the object has started moving in the opposite direction.
