Perform the following operation and express the answer in scientific notation. 1.26x104 + 2.50x104 [?]x10

1 answer:

4 0

Since your multiplying by the same number, 104, both terms, you can group them like this:
104(1.26+2.50)
104(3.76)
391.04

Knowing that scientific notation needs to be a number x, that’s greater or equal to 1, and less then 10.
3.9104 * 10^2

An object has a weight of 5.10 Newtons (N) at sea level, where the acceleration due to gravity is 9.81 m/s2.

RUDIKE [14]

Well, you could get the mass as $m=\frac{G_0}{g_0}$ ad then $g_1=\frac{G_1}{m}$ , where $G_0$ is the sea level weight, $g_0$ the sea level accel., $g_1$ the accel. above while $G_1$ the weight above.
