Answer:
v = 0.78 m/sec at 21.61° towards the east of north
Explanation:
Given a 19.3 kg dog is running northward at 2.98 m/s , while a 6.26 kg cat is running eastward at 3.64 m/s and the mass of the owner is 78.7 kg.
Given m(dog) = 19.3 kg and m(cat) = 6.26 kg
v(dog) = 
m/sec
v(cat) = 
m/sec
Given the 
Let the velocity of the owner be 
We know that 
v=0.78 m/sec
for direction
Tan(α)=
where α is the angle toward east of north.
Tan(α)=
α=21.61°

Answer:
There are three types of material as per the condition of charge flow
1) Conductor
2) Insulator
3) Semiconductor
1) Conductors
As we know that conductors are those which offer very small resistance to the flow of charge
Resistivity of the conductors are very small
2) Insulators
These type of materials offer large resistance to the flow of charges and it will not pass the current through it
So resistivity of the insulators are large as compared to conductors
Donna's doctor must have diagnosed her with muscle cramps. With the given symptoms above, it is likely that she is experiencing muscle cramps. Muscle cramps most likely happen when the individual experiencing it is lack of fluid intake, causing the muscles to tighten causing pain and for the muscle to contract involuntarily.
Answer:
3.85*10^8m
Explanation:
We know that
Speed v = distance/time t
So distance = v x t
So = 3*10^8 x 2.56s
= distatance = 7.7*10^8m
However this is double the distance from the earth to the moon, so to get distance from earth to the moon we divide by 2
7.7*10^8/2= 3.85*10^8m
