A : 10000 J
B: 625 J
C: 2500 J
Step-by-step explanation:
Step 1:
We know that ,
Kinetic Energy is given by ((1/2) × m × V²) J
where m = Mass of substance
V = Velocity
Step 2:
In first case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 20 ×20
= 10000 J
In second case, m= 50 kg, V=20 m/s
Kinetic energy = 0.5 × 50 × 5 ×5
= 625 J
In Third case, m= 50 kg, V=10 m/s
Kinetic energy = 0.5 × 50 × 10 ×10
= 2500 J
Answer:
5 ten thousands or fifty thousand
Step-by-step explanation:
millions, hundredthousand tenthousand thousands, hundreds tens ones.
3, 1 5 2 3 0 8
The five is in the ten thousands place
486 feet squared Is the answer
Answer:
C. 1/10
Step-by-step explanation:
To find the value of a digit in a number, set all the other digits to zero.
The value of the 5 in 634,952 is 000,050 = 50.
The value of the 5 in 43,597 is 00,500 = 500.
We want to find the multiplier k such that ...
50 = k×500 . . . . . . . 50 is "k" times 500
Divide by 500 to see ...
50/500 = k = 1/10
The value of 5 in the first number is 1/10 times the value of 5 in the second number.
