ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. In working on this problem, assume the value of "g" to be 9.8 m/s2 with two (2) significant digits unless otherwise stated.
Calculate the kinetic energy in joules of a 10 g bullet moving at 300 m/s.

J

A) 900
B) 450
C) 15
D) 45

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.

use photo math tells u all the answers thats what i use
