Answer:
DE HECHO EL SONIDO DÍ PUEDE ATRAVESAR LAS PAREDES, PERO
CUANDO ENTRA EN LA PARED, EL SONIDO VIAJA MÁS RÁPIDO QUE EN EL
AIRE Y CUANDO SALE DEL OTRO LADO, EL SONIDO VA A UNA
VELOCIDAD ALTA, POR ESTO LSA VOCES SE ESCUCHAN AUNQUE NO
MUY CLARAS.
Explanation:
Your pendulum does a complete swing in 1.9 seconds. You want to SLOW IT DOWN so it takes 2.0 seconds.
Longer pendulums swing slower.
You need to <em>make your pendulum slightly longer</em>.
If your pendulum is hanging by a thread or a thin string, then its speed doesn't depend at all on the weight at the bottom. You can add weight or cut some off, and it won't change the speed a bit.
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
