There's only one way
Explanation:
The duration of short term memory seems to be between 15 and 30 seconds. Items can be kept in short term memory by repeating them verbally (acoustic encoding), a process known as rehearsal.
Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
A nebula is an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars. The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases.
Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
Answer:
If the question is (2/3x) = -10,
x = -(1/15) = - 0.06667
The check is presented under the explanation below
If the correct question is (2/3)x = -10,
x = -15
The check is presented under the explanation below
Explanation:
If the question is rightly written as it is in the attached document,
(2/3x) = -10
We can cross multiply and obtain
2 = -10 × 3x
-30x = 2
x = -(2/30) = -(1/15) = - 0.06667
To check
(2/3x) = -10,
(2 ÷ 3x) = -10
2 ÷ 3(-1/15) = 2 ÷ (-1/5) = 2 ÷ (-0.2) = -10 (Correct!)
If the correct question is
(2/3)x = -10
Divide both sides by (2/3)
x = -10 ÷ (2/3)
x = -10 × (3/2)
x = -15
To check
(2/3)x = -10
If x = -15
(2/3) × (-15) = -10 (Correct!)
Hope this Helps!!!
