Answer: 98 millimeters
Explanation:
Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that
(1)
Since x= VK = VY + YK, we need to obtain VY since YK = 68.
VY is obtained by multiplying the denominator YK on both sides of equation (1). So,
Hence,
x = VK = VY + YK
x = 30 + 68
x = 98 millimeters
Answer:
140.85 is the correct answer
Answer:
a= 2.5m/s²
Explanation:
U=0
V=90km/hr
T= 10s
Convert 90km/hr to m/s
1km= 1000m
1hr= 3600s
(60×60)
therefore, 90km/hr = 90000/3600
90km/hr= 25m/s
From Newton First Equation,
V=U + AT
25=0+ A(10)
25= 10A
25/10 =10A/10
A= 2.5m/s²
Answer:
145 degree
Explanation:
We are given that
Magnetic field=B=2 T
Charge on particle,q=
Velocity, v=
Angle,
We have to find the direction of the force exerted on this particle by magnetic field with magnitude 2 T in the z direction.
Component of velocity along x- axis
Along y- axis
Hence, the direction of force =145 degree
