Explanation:
The given data is as follows.
Length of beam, (L) = 5.50 m
Weight of the beam, (
) = 332 N
Weight of the Suki, (
) = 505 N
After crossing the left support of the beam by the suki then at some overhang distance the beam starts o tip. And, this is the maximum distance we need to calculate. Therefore, at the left support we will set up the moment and equate it to zero.

= 0
x = 
= 
= 0.986 m
Hence, the suki can come (2 - 0.986) m = 1.014 from the end before the beam begins to tip.
Thus, we can conclude that suki can come 1.014 m close to the end before the beam begins to tip.
In the direction the force is directed towards. If the boy kicks the ball to the right, the ball will roll to the right.
Answer:
0.64 J/g°C
Explanation:
Using the formula;
Q = m × c × ∆T
Where;
Q = amount of heat
m = mass (g)
c = specific heat capacity
∆T = change in temperature (°C)
In this case:
Q (water) = - Q (metal)
mc∆T (water) = - mc∆T (metal)
According to the information in this question,
For water; m = 100g, c = 4.18J/g°C, ∆T = (25°C - 20°C)
For metal; m = 50g, c =?, ∆T = (25°C - 90°C)
mc∆T (water) = - mc∆T (metal)
100 × 4.18 × (25°C - 20°C) = - {50 × c × (25°C - 90°C)}
100 × 4.18 × 5 = - {50 × c × -65}
2090 = -{-3250c}
2090 = 3250c
c = 2090/3250
c = 0.643
c = 0.64J/g°C
Answer:
I don't really know much about the whole stars thing, but I've written a lot of paragraphs in science
Explanation:
Remember:
- A paragraph should be in CER formation: Claim (hypothesis/discovery), Evidence, and Reasoning
- Your reasoning should never start with I believe or I think, your reasoning and evidence are 100% fact based
- The actual hypothesis should only be 1-2 sentences and be straight to the point
Include:
- for your hypothesis, keywords relating to your subject, I'm assuming for your topic you should include things like marking, telescope, stars, etc.
- why you believe your hypothesis is true
- so use prior knowledge to justify your hypothesis
