Answer:
towards west
Explanation:
As we know that the speed of the blue car as appear to the bicycle rider is given as
towards west
also it is given that bicycle is moving at speed of 10 km/h towards East
so here we have

so we have

towards west
now speed of the red car is given as 15 km/h towards west
so here the relative speed of blue car with respect to red car is given as

towards west
Answer: well the time it takes to fall 100m is the same time it takes to travel 65m horizontally.
The time to fall vertically, t is sqrt(2d/g). [this comes from d = 1/2at^2]
so t = sqrt(2*100/9.8) = 4.52s.
The vertical speed at that time is g*t = 9.8*4.52 = 44.3m/s
The horizontal speed is the horizontal distance over the same 4.52s, = 65/4.52 = 14.4m/s.
so the final velocity is = sqrt(44.3^2 + 14.4^2) = 46.6m/s
Explanation: yes
Answer:
Only the 4 th statement is true that is bed 1 and 3 are older than 4.
Explanation:
The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.
We are given 4 statements and we have to find out which all are true.
(<u>a)Bed 4 is older than bed 2 </u>
This is wrong because the lower beds are older than beds that are higher.
<u>(b)Bed 3 is older than beds 2 and 4</u>
This is also wrong because the 2 is older than 3
(<u>c)Bed 5 is the oldest </u>
This is wrong because bed 1 is the oldest
(<u>d)Beds 1 and 3 are older than 4</u>
This is true as lower beds are older

The formula (ma = F - Fg) is used to determine the net upward force acting on a body.
<h3>
What is net upward force acting on a body?</h3>
The net upward force acting on a body is the resultant or sum of all the upward forces acting on a body at a given time.
ma = F - Fg
where;
- F is the applied force
- Fg is the force of gravity
- ma is the resultant force
Thus, the formula (ma = F - Fg) is used to determine the net upward force acting on a body.
