Explain why when a firefighter rescues a dog that has fallen through ice on a
lake, they put their ladder on the ice first and then crawl out to the dog on the
ladder.
Answer:
This can spread their weight.
Explanation:
The ladder has a much larger surface area than the firefighter. Hence, his weight is spread out much more than usual, decreasing the pressure on the ice, preventing the ice from breaking/cracking.

To illustrate the use of a multistage rocket consider the following:
(a) A certain rocket carries 60% of its initial mass as fuel. (That is, the mass of fuel is 0.6mo) What is the rocket's final speed, accelerating from rest in free space, if it burns all its fuel in a single stage? Express your answer as a multiple of v ex .
(b) Suppose instead it burns the fuel in two stages as follows: In the first stage it burns a mass 0.3m o of fuel. It then jettisons the first-stage fuel tank, which has a mass of 0.1m o , and thenburns the remaining 0.3m 0 of fuel. Find the final speed in this case, assuming the same value of vex throughout and compare.
Answer:
a
[tex]v_f = 0.916 v_{ex}[/tex]
b
[tex]v_f = 1.05 v_{ex}[/tex]
Explanation:
Considering question a
From the question we are told that
The mass of the rocket is [tex]m_o[/tex]
The mass of the fuel which is in the rocket is m = 0.6 M
Generally given that the rocket burns all it fuel in a single stage , the final velocity of the rocket is mathematically represented as
[tex]v_f = v_{ex} ln [\frac{m_o}{m_k} ][/tex]
Here [tex]m_k[/tex] is the mass of the rocket without fuel which is mathematically evaluated as
[tex]m_k = m_o- m[/tex]
=> [tex]m_k = m_o -0.6m_o[/tex]
=> [tex]m_k = [1- 0.6] m_o[/tex]
=> [tex]v_f = v_{ex} ln [\frac{m_o}{[1 - 0.6]m_o} ][/tex]
=> [tex]v_f = 0.916 v_{ex}[/tex]
Considering question b
From the question we are told that
The mass of the fuel it burn at the first stage is [tex]m = 0.3 m_o[/tex]
The mass of the first stage fuel tank [tex]m_1 = 0.1 m_o[/tex]
The mass of the fuel at the second stage is [tex]m_f = 0.3m_o[/tex]
Generally the velocity of the rocket at the first stage is mathematically represented as
[tex]v_i = v_{ex} * ln [ \frac{m_o }{[1- m]m_o } ][/tex]
=> [tex]v_i = v_{ex} * ln [ \frac{m_o }{[1- 0.3]m_o } ][/tex]
=> [tex]v_i = v_{ex} * ln [ \frac{1 }{0.7 } ][/tex]
=> [tex]v_i =0.357 v_{ex}[/tex]
Generally the mass of the rocket after first stage is
[tex]m_r = m_o - 0.3m_o -0.1m_o[/tex]
=> [tex]m_r = 0.6m_o[/tex]
Generally the final velocity of the rocket at the second stage is
[tex]v_f = v_i + v_{ex} * ln [\frac{m_r}{ m_f } ][/tex]
=> [tex]v_f = v_i + v_{ex} * ln [\frac{0.6 m_o }{0.3mo } ][/tex]
=> [tex]v_f = 0.357 v_{ex} + 0.693 v_{ex}[/tex]
=> [tex]v_f = 1.05 v_{ex}[/tex]
observe the figure given carefully volume of water in each vessel is shown arrange them in order of decreasing pressure at the base of each vessel explain the reason
Answer:
See the explanation below
Explanation:
The pressure is defined as the product of the density of the liquid by the gravitational acceleration by the height, and can be easily calculated by means of the following equation.
[tex]P=Ro*g*h[/tex]
where:
Ro = density of the fluid [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation [m]
In this way we can understand that the greater pressure is achieved by means of the height of the liquid, that is, as long as the fluid has more height, greater pressure will be achieved at the bottom.
Therefore in order of decreasing will be
The largest pressure with the largest height of the liquid, container B. The next is obtained with container D, the next with container A and the lowest pressure with container C.
The pressure decreases as we go from the container B - D - A - C

In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8
seconds. If the ball had a change in velocity, Av, of 50 m/s, what is the mass of the ball?
Answer:
Mass, m = 32 kg
Explanation:
Given that,
Force, F = 2000 N
The change in velocity, (v-u) = 50 m/s
Time, t = 0.8 s
We need to find the mass of the ball. The net force acting on an object is given by :
F = ma
Where a is acceleration
[tex]F=\dfrac{m(v-u)}{t}\\\\m=\dfrac{Ft}{(v-u)}\\\\m=\dfrac{2000\times 0.8}{50}\\\\m=32\ kg[/tex]
So, the mass of the ball is 32 kg.
The photo shows two yeast cells. Each cell is an individual organism. Which sentence best describes what happened to each cell during cell growth?
A. It will become many different cells.
B. It will produce offspring with a mate.
C. It will divide in half to form two new cells.
D. It will become larger by taking in nutrients.
The answer is option c - It will divide in half to form two new cells..
Explanation:
The sentence that best describes what happened during cell growth is ;
( D ) It will become larger by taking in nutrients
As the yeast cells begin to grow ( i.e. cell growth ), they will require more nutrients and as they take in the necessary nutrients they will gradually increase in size ( becoming larger ) which is a vital sign of cell growth and development, which will be seen in the yeast cells as they undergo cell growth.
The production of offsprings with a mate does not describe an activity that occurs in cell growth.
Hence we can conclude that The sentence that best describes what happened during cell growth is, It will become larger by taking in nutrients.

A stone is thrown straight up. While the stone is rising:
A. its acceleration is upward and decreasing
B. its acceleration is upward and constant
C. its acceleration is upward and increasing
D. its acceleration is zero
E. None of the above.
Answer:
D. its acceleration is zero
Explanation:
Acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
In this scenario, a stone is thrown straight up. While the stone is rising its acceleration is zero because it's initial velocity is zero and it's until the stone reaches its highest point before the acceleration becomes constant and acting downward.

The bike skids 41.5 m 41.5m41, point, 5, start text, m, end text with constant acceleration before it comes to a stop. What was the acceleration of the motorbike as it came to a stop?
Answer:
Explanation:
Initial velocity , u = 27 m/s
displacement before stop, s = 41.5 m .
final velocity, v = 0
acceleration a = ?
v² = u² + 2 a s
0 = 27² + 2 x a x 41.5
a = - 27² / 2 x 41.5
= - 8.78 m /s
A machine that operates a ride at the fair requires 2500 J to lift a 294 N child 5.0 m. What is the efficiency of this machine?
Answer:
η = 58.8%
Explanation:
Work is defined as the force applied by the distance traveled by the body.
[tex]W =F*d[/tex]
where:
W = work [J] (units of joules)
F = force = 294 [N]
d = distance = 5 [m]
[tex]W = 294*5\\W = 1470 [J]\\[/tex]
Efficiency is defined as the energy required to perform an activity in relation to the energy actually added to perform some activity. This can be better understood by means of the following equation.
[tex]efficiency = W_{done}/W_{required}\\efficiency = 1470/2500\\efficiency = 0.588 = 58.8%[/tex]
