Jimmy wanted to create a study to test the effects of jazz on people's sleep patterns. He thought that if people listened to jaz

z music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of 10 people were created. The test was conducted in a sleep lab
facility with each room being exactly identical. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played
softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.

The gravitational force, F, on a rocket at a distance, from the center of the earth is given by F = k / (r^2), where k = 10 ^3 n
makvit [3.9K]
F = k / (r^2)
dF/dt = -2k / (r^3) dr/dt

When r = 10^4 km and dr/dt = 0.2 km/sec
dF/dt = -2(10)^3 (0.2) / ((10^4)^3) = -400 / 10^7 = -0.00004 N/s

The gravitational force is changing at the rate of -0.00004 N/s

Square ABCD is shown below.
valentina_108 [34]

Answer:

35 is the length of BE

Step-by-step explanation:

2(2x + 5) = 8x - 50

4x + 10 = 8x -50

10+50 = 8x-4x

60= 4x

15 = x

2x + 5 = length of BE equal to length of DE

2(15) +5 = BE

30 +5

35 is the length of BE
