Answer:
m uncertainty percentage :
+- 2.5
+- 7.5
+- 12 5
+- 17.5
+- 25
+- 30
M uncertainty percentage = 16.5
m + M uncertainty percentage;
+- 19
+- 24
+- 29
+-34
+- 41.5
+- 46.5
ex 50 × 5 ÷100 = 2.5
Answer:
264,600J
Explanation:
Gpe = mgh, knowing that the acceleration due to gravity,g, is 9.8N/kg.
Answer:
The scientific method helps test and arrive at conclusions for a variety of hypotheses that are created when studying environmental science.
Explanation:
What is the scientific method in environmental science?
The scientific method is a method of research with defined steps that include experiments and careful observation. One of the most important aspects of this method is the testing of hypotheses by means of repeatable experiments. A hypothesis is a suggested explanation for an event, which can be tested.
Answer:
100
Explanation:
= Resistivity of axon
r = Radius of axon
t = Thickness of the membrane
= Resistivity of the axoplasm
Speed of pulse is given by
So, radius is given by
If radius is increased by a factor of 10 new radius will be
So, The radius will increase by a factor of 100.
Answer: 495.05 m
Explanation:
Given:
Initial velocity of the bullet, u = 1000 m/s, mass of the bullet, m = 10 g, mass of the wooden block, M = 1000 g,
From the swinging of the wooden block just after the collision with the bullet to its maximum height, using conservation law of mechanical energy we have that,
1/2(m+M) = (m+M)gh
Where h = the vertical height of the block in the direction will the block swing, and g = acceleration due to gravity = 10
=> v=
Using the conservation law of linear momentum,
mu = (m+M)v
mu = (m+M) (where v=)
=>h = *
h=
