about 12 hours I think, since there are two high tides per day
Answer
given,
mass of the goalie(m₁) = 70 kg
mass of the puck (m₂)= 0.11 kg
velocity of the puck = 31.5 m/s
elastic collision
Answer:
72 minutes
Explanation:
The combined rate of the two machines is 250 bolts/hr:
(100 bolts/hr) + (150 bolts/hr) = 250 bolts/hr
The number of bolts is equal to the rate multiplied by time, therefore an expression for time can be found:
Bolts = (rate)(time) >> Time = (bolts)/(rate)
The time necessary to make 300 bolts is:
Time = (bolts)/(rate)
Times = (300 bolts) / (250 bolts/hr) = 1.2 hr
The time in hours is converted to time in minutes as follows:
(1.2 hr) (60 min/hr) = 72 minutes
Answer:
ma= ma
m⋅a = m⋅a
And equivalently:
am=ma
a⋅m = m⋅a
Explanation:
Question
Assuming this question "Similar to what you see in your textbook, you can generally omit the multiplication symbol as you answer questions online, except when the symbol is needed to make your meaning clear. For example, 1*10^5 is not the same as 110^5 . When you need to be explicit, type * (Shift + 8) to insert the multiplication operator. You will see a multiplication dot (⋅) appear in the answer box. Do not use the symbol x. For example, for the expression ma,
typing m⋅a would be correct, but mxa would be incorrect".
Solution to the problem
For this case we want to write a expression for ma, and based on the previous info we can write:
ma= ma
m⋅a = m⋅a
And equivalently:
am=ma
a⋅m = m⋅a
But is not correct do this:
mxa=mxa
axm = mxa
