Answer:
60 km/h
Explanation:
In the first part of the trip, the speed is
v = 80 km/h
while the time interval is
t = 3 h
So, the distance covered is:
d = vt = (80)(3)= 240 km
The problem states that this distance is half distance between home and the destination - so, the total distance between home and the destination is
The time taken to cover the second part of the trip is 5 h, so the total time taken is
T = 3 h + 5 h = 8 h
Therefore, the average velocity for the entire trip is
Answer:
The value of the time constant is 558.11 sec.
Explanation:
Given that,
Pendulum length = 1 m
Initial angle = 15°
Time = 1000 s
Reduced amplitude = 2.5°
We need to calculate the value of the time constant
Using formula of damping oscillation
Where, 
=amplitude
=amplitude at t = 0
Put the value into the formula
Hence, The value of the time constant is 558.11 sec.
A) Beneficial insects (e.g a bee) may be adversely affected
The June solstice in the Northern hemisphere is the summer solstice. The June Solstice in the Southern hemisphere is the winter solstice. The summer solstice is equivalent to the longest day while the winter solstice is equivalent to the shortest day. Therefore on the local sky, when is the June solstice we have have the longest day (longest path of sun in the sky) in the Northern hemisphere and the shortest day (shortest path of sun in the sky) in the Southern hemisphere.
Well if shes at a beach i would think that the sun is out and because of radiation they're gonna get hot. somebody should probably warn her or she's gonna burn her feet
