Answer:
The greenhouse affect is what traps the Sun’s heat or rays/ temperature in our atmosphere which causes our global warming
Explanation:
While most constellations are only visible to us in different seasons, some are always there 24/7/365 because they are positioned close to the Polar Axis, or the Polaris.
C) volume
.........
The volume of gas depends on e.g. temperature and pressure.
Answer:
Explanation:
Pv = n RT
P =7.65, T= 310K, for glucose n = moles= weight/molar mass= weight/180, R is gas constant
7.65* V =W/180 *0.0821 * 310
w/v= 7.65*180/0.0821*310 = 1377/25.45 = 54.10 =5.4%
Car B and E are speeding up, while car C is slowing down.

What is Velocity ?</h3>
Velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.
Step-by-step explanation :
Acceleration (a) is the rate of change of velocity with time.
It is calculated by dividing the change in velocity (Δv) with the time taken for the change to occur.
In this question , the time is 10 sec in all cases.
We can divide the velocity in km/h by 3.6 to convert to m/s
In Car A
Δv = 8.33-8.33 = 0m/s
t = 10s
a = 0 m/s² ⇒car is moving with same speed and in the same direction
Car B
Δv = 5.55-0 = 5.55
t = 10
a = 5.55 / 10 = 0.555 m/s² ⇒car is speeding up
Car C
Δv = 0 - 8.33 = -8.33 m/s
t = 10
a = - 8.33/10 = -0.833 m/s² ⇒car is slowing down
Car D
Δv = 0-0 = 0
t = 10s
a = 0/10 = 0 m/s² ⇒car is at rest
Car E
Δv = 8.33 - 5.55 = 2.78
t = 10
a = 2.78/10 = 0.278 m/s²⇒car is speeding up
