Answer:
<em>Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip</em>
Explanation:
<u>Proportions and Ratios</u>
To compare two quantities we can perform them some 'test' operations like subtraction or division. If we subtract the first quantity from the second quantity, the difference can be positive if the second is greater, negative if the first is greater, or zero if they are equal.
A similar situation comes if we divide the last by the first. If the ratio (division) is greater than one, then the last quantity is greater than the first if it's less than one, the first is greater, and if it's exactly one, they are equal.
Zoe caught 9 catfish and 6 trout on her first day. It produces a ratio of 9/6=1.5 catfish to trout relation. The second day she caught 17 catfish and 13 trout, which gives us a ratio of 17/13=1.3 catfish to trout.
Based on the ratios we can say Zoe caught a lower ratio of catfish to trout on the second day of her fishing trip
Answer:
raise the board to a higher angle
Explanation:
Static friction is the force opposite to the applied force.
Static friction is dependent on the angle of inclination, it means as the angle of incline increases, the force of friction will increases as normal force will decrease.
So, if the board will be raised to a higher angle, it will increase the angle of incline and will overcome the static friction and block will be able slide.
Hence, the correct option is "raise the board to a higher angle".
Answer:
Distance = 25000000 miles
Time = 50 hours
Explanation:
Venus is the closest planet to Earth. It is about 25 million miles away from Earth. Its precise distance depends on where both Venus and Earth are in their respective orbits
Given that
Speed V = 500000 mph
Distance d = 25 000,000 miles
Speed = distance/ time
Time = distance/speed
Time = 25000000/500000
Time = 50 hours
It will therefore take 50 hours to get to venus at that speed.
Answer:
M=125 kg
v=1.75 m/s
Explanation:
From the law of linear momentum
P =mv
Case 1 50*V =M* 0.7 equation 1
50*V =(M+50)* 0.5 equation 2
equating 1 and 2
M* 0.7=(m+50)* 0.5
0.2 M= 25
M=125 kg
Putting value of M in equation 1
50*V =125*0.7
V=1.75 m/s
Displacement is a vector quantity. So, you incorporate the vector calculations when you try to determine the resultant vector. This is the shortest path from the starting point to the endpoint. If they are moving on one axis only, you use sign conventions. For motions moving to the left, use the negative sign. If it's moving to the right, then use the positive sign. Now, it the object moves 2 km to the left, and 2 km also to the right, the displacement is zero.
Displacement = 2 km - 2km = 0
Generally, the equation is:
<span>Displacement = Distance of motion to the right - Distance of motion to the left</span>
