A steel ball and a wooden ball of the same diameter are released together from the top of a tower. In the absence of air resista

nce they both would reach the ground at the same time. The reason for this is that the force on each ball is the same.True / False.

Answer:

False

Explanation:

The steel ball and the wooden ball do not have the same force acting on them because their masses are different. But, they have the same acceleration which is the acceleration due to gravity g = 9.8 m/s².

Using the equation of motion under freefall, s = ut +1/2gt². Since u = 0,

s = 1/2gt² ⇒ t = √(2s/g)

Since. s = height is the same for both objects, they land at the same time neglecting air resistance.

Answer:

Sophie

Explanation:

Only Sophie's results supported Newton's second law. The other students' measured accelerations were significantly lower than expected. This could indicate that their experimental designs had not sufficiently eliminated drag forces.

F=ma         Rearranging when solving for acceleration gives:  a=F/m

What is .00245 in scientific notation?
Sloan [31]

Answer:

2.45 x 10^-2

Explanation:

All numbers in scientific notation or standard form are written in the form

m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.

To convert 0.0245 into scientific notation, follow these steps:

Step 1) Move the decimal 2 times to right in the number so that the resulting number, m = 2.45, is greater than or equal to 1 but less than 10

Step 2) Since we moved the decimal to the right the exponent n is negative

n = -2

Step 3) Write in the scientific notation form m × 10n

= 2.45 × 10-2

Therefore,

2.45 × 10-2 is the scientific notation form of 0.0245 number and 2.45e-2 is the scientific e-notation form for 0.0245

Here are some examples of decimal to scientific notation calculator
