Explanation:
Solution:
Let the time be
t1=35min = 0.58min
t2=10min=0.166min
t3=45min= 0.75min
t4=35min= 0.58min
let the velocities be
v1=100km/h
v2=55km/h
v3=35km/h
a. Determine the average speed for the trip. km/h
first we have to solve for the distance
S=s1+s2+s3
S= v1t1+v2t2+v3t3
S= 100*0.58+55*0.166+35*0.75
S=58+9.13+26.25
S=93.38km
V=S/t1+t2+t3+t4
V=93.38/0.58+0.166+0.75+0.58
V=93.38/2.076
V=44.98km/h
b. the distance is 93.38km
Answer:
<u><em>conditional positive regard</em></u>
Explanation:
Condition Positive Regard can be described as a situation in which positivity, love or affection are only given when certain criteria or demands are met. Whereas on the contrary, an unconditional positive regard occurs when a person is loved without any demands or criteria.
Condition positive regards means to love or show affection for someone or something depending on its values in our eyes.
Answer:
C
Explanation:
When trash accumulates, astronauts manually squeeze it into trash bags, temporarily storing almost two metric tons of it for relatively short durations, and then send it away in a departing commercial supply vehicle, which either returns it to Earth or incinerates it during reentry through the atmosphere.
Answer:
(A) 0.3488 rad/sec
(B) 124.246 m
Explanation:
We have given car completes one revolution in 18 sec'
So time period T= 18 sec
Tangential speed v = 43.4 m/sec
(A) Angular velocity is given by 
(B) Tangential velocity is given v = 43.4 m /sec
We know that 
The electron near the Earth's equator doesn't deflect if it's velocity is directed downwards.
Assume that north is directed along upwards, south is directed along downwards, east is directed along rightwards, and west is directed along leftwards.
The magnetic force on the charge q, moving with velocity v in the magnetic field B is given by
F=q(→v×→B)=qvBsinθ ..(1)
Here,
θ is the angle between the magnetic field and velocity.
Inside the Earth, the Earth's magnetic field is along northward (upwards), and the velocity is given to be along southwards (downwards) making an angle of 180°. In equation (1) sin180°=0. So, no magnetic force acts on the electron
Therefore,
The electron didn't deflect if it is directed downwards.
