Answer:
6.7 /s.
Step-by-step explanation:
Initial velocity = u m/s
From the question, final velocity, v = - 2u m/s
Note - (the minus sign indicates that the direction was reversed and doubled)
t = 0.45
From equation of motion,
v = u + at
Acceleration, a = (v - u)/t
= (-2u - u)/0.45
= - 3u/0.45
Acceleration, a/Original speed, u = 3/0.45
= 6.7 /s
Answer:
False
Step-by-step explanation:
We find the volumes of the two cubes and compare them.
volume of cube = side^3
The volume of the 10-cm cube is:
V = (10 cm)^3 = 1000 cm^3
The volume of the 5-cm cube is:
V = (5 cm)^3 = 125 cm^3
1000/125 = 8
The volume of the 10-cm cube is 8 times the volume of the 5-cm cube.
The statement is false.
Answer:
a) 5y²
Step-by-step explanation:
5 divided by 1 is still 5
y^5/y^3 subtract the exponents since the base is the same
800,000 is the correct answer
104 is 8 times 13. but working 8 hours 7 days equals 56 times the hourly pay comes out to 728
