Explanation:
A canister is approaching a 78.4 kg astronaut at 3.5 m/s in an airless spacecraft. She pushes against it, which slows it down to 1.2 m/s (but does not reverse it) and gives her a speed
of 2.4 m/s. What is the mass of this canister?
76.3 kg
55.6 kg
81.8 kg
90.0 kg

Explanation:
A 57 kg ice skater moving to the right with a velocity of 1.2 m/s throws a 0.11 kg snowball to the right with a velocity of 31.5 m/s relative to the ground. What is the velocity of the ice skater after throwing the snowball? Disregard the friction between the skates and the ice.
Answer:
v_f = 1.14 m / s
Explanation:
This is an exercise of conservation of momentum, let's define a system formed by the skater and the snowball, therefore the forces during the launch are internal and the moment is conserved.
Initial instant. Before throwing the ball
p₀ = M v₀
Final moment. After throwing the snowball
p_f = (M-m) v_f + m v
the moment is preserved
p₀ = p_f
M v₀ = (M-m) v_f + m v
v_f = [tex]\frac{M v_o - m v}{M-m}[/tex]
let's calculate
v_f = [tex]\frac{57 \ 1.2 - 0.11 \ 31.5}{ 57 - 0.11}[/tex]
v_f = 64.936 / 56.89
v_f = 1.14 m / s
HOW DOES A GRAPH HELP YOU SEE ANOMALOUS DATA?
Answer:
Anomalies consist of one or more modifications, insertions or deletions. As was described in Section 3.1, there are only three types of changes that can be made to a graph. Therefore, anomalies that consist of structural changes to a graph must consist of one of these types. Assumption 4.

Explain why the temperature varies with distance from the Sun in this way?
Answer:
The average surface temperature decreases the further you get from the Sun because the more distant planets receive less energy/heat/sunlight per square meter of their surface. This is because the energy from the Sun spreads out (becomes less concentrated) as you travel further from the source/Sun.

what effect does the earth's surface have on solar radiation?
A. The ground absorbs half the solar radiation and stored it as infrared radiation for centuries
B. Half of the solar radiation is absorbed and converted to infrared (heat)
C. Nearly all solar radiation is reflected back into space by the ground
Answer:
B.
Explanation:
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
Hope this helps, sorry if it is incorrect. Have a great day/night!

What is solar radiation?Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun.
Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies

Osmium, is the densest metal found,has density of 22.6 g/cm 3. The mass of the block is 113 g. Find its volume. (1 mark for formula and 1 mark for showing calculation)
Answer:
Volume = 5 cm³
Explanation:
Given the following data;
Density = 22.6 g/cm³
Mass = 113 grams
To find the volume;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Making volume the subject of formula, we have;
[tex]Volume = \frac{mass}{density}[/tex]
Substituting into the equation, we have:
[tex]Volume = \frac{113}{22.6}[/tex]
Volume = 5 cm³
People living wind farms sometimes object to them because of visual pollution and what other form of pollution?
Answer:
noise pollution
Explanation:
Visual pollution may be defined as a pollution that obstructs a view. It impairs one ability to see and enjoy a pleasant view. It is considered as an aesthetic issue.
The rotating blades of the windmill causes visual disturbances by intercepting the light of the sun and it causes moving shadows and the light flashes from the reflection of the sun. It also causes noise or sound as the blades rotates. Thus the combination of visual and acoustics exposures leads to the negative assessment of the windmills.
Therefore, people living near wind farms objects the windmills as they causes visual pollution as well as noise pollution.

1) velocity = displacement/time
time = displacement/velocity
time = 200/660
= 10/33
= 0.303
2) vf = vi - a*t
0 = 30 - 9.8*t
t = 30 ÷ 9.8

A ball is initially moving with a velocity 0.5m/s. Its velocity decreases at a rate of 0.05m/s^2. How much time will it take to stop? How much distance will the ball travel before it stops
Answer:
I think its 1
Explanation:
The reason why I think it's 1 is because 0.5m/s^2 /0.5 m/s= 1 s
