The vertical components of velocity is 10.35 m/s and the horizontal component of velocity is 38.6 m/s
<h3>What are the components of velocity?</h3>
We know that velocity is a vector quantity, a vector often can be resolved into its components. The vertical components is V sinθ while the horizontal component is vcosθ.
Hence;
Vertical component = 40 m/s sin 15 degrees = 10.35 m/s
Horizontal component = 40 cos 15 degrees = 38.6 m/s

Answer:
18kg dog walking
Explanation:
the dog walking has more inertia than the boy and girl because its gravity is pulling it down to the earth
For the answer to the question above, each horse's force forms a right angle triangle with the barge and subtends an angle of 60/2 = 30°. The resultant in the direction of the barge's motion is:
Fx = Fcos(∅)
We can multiply this by 2 to find the resultant of both horses.
Fx = 2Fcos(∅)
Fx = 2 x 720cos(30)
Fx = 1247 N
The biomass energy can use improve water quality in soil erosion and sedimentation are decreased during biomass crop growth. The correct option is C.
<h3>What is biomass energy?</h3>
Biomass energy is obtained by the processing of the dead plants and animal or vegetable, cow dung or wood.
The biomass energy obtained by these bio things, it is enriched with the nutrients required by the new crop plants to grow effectively.
The biomass energy provides good water quality by soil erosion and sedimentation.
Thus, The correct option is C.

<span>We need to calculate the resistance of a clock which draws current I=0.5A and is connected to a circuit of V=120V. We can find the resistance of a circuit from Ohm's law: I=U/R where I is the current, U is the voltage and R is the resistance. So lets manipulate Ohm's law to find the resistance: R=U/I. Now we input our numbers: R=120V/0.5A and we get R=240 Ohm. So the resistance is R=240 Ohm.</span>
