Answer:
- See the graph attached with the vectors.
Explanation:
The exercise is to draw the corresponding vectors:

Every one is the multiplication of a scalar by a vector.
The result of multiplying a scalar by a vector is a vector with the same direction of the original vector enlarged in a factor equal to the scalar magntitude.
Thus, in a graph the resulting vector is represented with a parallel arrow and pointing in the same direction as the original vector but with a length equal to the original length multiplied by the magnitude of the scalar.
For instance, the vector
is represented with an arrow in the same direction of
and with twice its length.
The figure attached contains the five requested vectors using the procedure explained above.
Answer:
Heat generated in the rod is 8.33 watts.
Explanation:
It is given that,
Length of rod, l = 2 m
Area of cross section, 
Resistivity of rod, 
Potential difference, V = 0.5 V
The value of resistance is given by :


R = 0.03 ohms
Let H is the rate at which heat is generated in the rod . It is given by :

Since, 



So, the at which heat is generated in the rod is 8.33 watts. Hence, this is the required solution.
Answer: weight on Jupiter = 869.75 N
mass on Earth = mass on Jupiter = 35.5 Kg
Explanation:
W = mg
W = weight
m = mass
g = gravitational acceleration [ on the Earth, g₁ = 9,8 N/kg ]
On the Earth,
G₁ = m x g₁ = 347,9 N
On the Jupiter,
G₂ = mg₂
mass on the Earth = mass on the Jupiter !
m = G₁ : g = 347.9 N : 9,8 N/kg = 35.5 kg
G2 : G1 = 2.5
G₂ = 2,5 G₁ = 2,5 x 347.9 N = 869,75 N
Answer:
= 1000 hours
Explanation:
Earth's circumference is 10⁴ mile
speed of a sailboat is 10¹ mile/hour
distance = speed × time
10⁴ = 10¹ × t
t = 10⁴ / 10¹
t = 10³
= 1000 hours
Hey there!
A seed can be round when parents are crossed, scientists refer to the first generation of offspring as F1. <span> This is the first generation of seeds from very different parental types.</span><span>
