Let the distance between points a and b = d
For the women starting from a her velocity be 
and for the women starting from b her velocity be 
Let the rising time of sun = x AM
We have = 
and we also have = 
At they meet means, they both travel a combined distance of d
So we have 
Substituting velocity values we will get
x= 6 AM or 18 AM, but 18 AM is not possible,
Sun rise time is 6 AM
Answer: They are identical brightness
Explanation:
If the lights are assumed to be resistance bulbs
Each light has the same current and will each drop one third of the supply voltage.
Answer:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.
Answer:
The force from the truck on the car is always equal to the force from the car on the truck.
Explanation:
According to Newton's third law; action and reaction are equal and opposite. Hence, when the big truck and small passenger car are involved in a collision, we expect that the force from the truck on the car is always equal to the force from the car on the truck. The forces on the car and the truck are equal in magnitude but opposite in direction.
This follows directly from Newton's third law of motion hence the answer above.
Answer:
Yes
Explanation:
The plank (also called a front hold, hover, or abdominal bridge) is an isometric core strength exercise that involves maintaining a position similar to a push-up for the maximum possible time
