Answer:
4.7 × 10⁵J
Explanation:
E = I * a * t
80% = 0.80
25cm = 0.25m
52cm = 0.52m
0.90h = 3240s
E = (0.80)(1400)(0.25 * 0.52)(3240)
= 4.7 * 10⁵J
The flame on a gas stove heats the bottom of a metal pot is conduction.
The sun gives you a sunburn is a radiation
Answer:
16 Newtons
Explanation:
We will use the equation F=ma
First, find the acceleration using the givens.
a=∆v/∆t
a=15-3/3
a=12/3
a=4 m/s^2
Next, plug the acceleration and mass into the equation.
F=ma
F=4kg(4m/s^2)
F=16 Newtons
2y²-18xy+2x²
