Answer:
Length = 155.6 m
Explanation:
given data
mass = 700 kg
total resistance = 4300 N
tension = 12000 N
speed = 40 m/s
solution
we get here equation for glider in the back and front
for the glider in the back
T - 2400 = 700 a ...........1
for the glider in front
12000 - T - 2400 = 700a .............2
now we add both these equations
12000 - 4800 = 1400 a .............3
a = 5.14 m/s²
and
now we use equation of motion
v² - u² = 2 a S .............4
40² = 2 × 5.14 × S
so
Length = 155.6 m
Answer:
Yes
Explanation:
But I feel also 2 is correct but your answer is right
Given:
B(Magnetic field): 1.5 T
q= 7.5 microcoulombs
v= 1.75 x 10 ∧6 m/s
The angle ∅ between B and v is 45 °.
Now we know that F= qvB sin ∅
Substituting these values we get:
F= 7.5 x 10∧-6 x 1.75 x 10∧6 x 1.5 x sin 45
F= 16.752 N
A. The Sun is the only star in the Solar System. This is the only star we know of.
I hope this helps!!
