Answer:0.0242 Nm
Explanation: The distance of 0.145 mm is very small. This will also result in a small ttorque. The question would make more sense if the distance was 0.145 m. Answering with the 0.145 mm as distance :
Changin from mm to m : 1mm=0.001m
0.145 mm = 0.000145 m
The formula for Torque is T=Fxd
Wher F is the force and d is the perpendicular distance between the centre of the bolt and the applied force.
T= 167 x 0.000145 = 0.024215 Nm
Answer:
260 km/h
Explanation:
Motion is said to be relative when the motion observed by the observer depends on the location (frame) of the observer.
When two objects are moving in opposite directions, the relative motion is obtained by subtraction.
Hence the plane is moving at (285 - 25) km/h giving 260 km/h
<span>5 seconds expired during the deceleration.
Top rotated 45 radians during these 5 seconds.
First, calculate the chance in velocity, by subtracting the initial velocity from the final velocity. So
6 rad/s - 12 rad/s = -6 rad/s
So we lost a total of 6 rad/s. Divide that by the deceleration to give the number of seconds. So
-6 rad/s / -1.2 rad/s^2 = 5 s
So it takes 5 seconds for the deceleration to happen.
The equation that expresses the number of radians performed under constant deceleration with an initial velocity is
d = VT + 0.5 AT^2
where
d = distance
V = initial velocity
T = time
A = acceleration
Substituting the known values gives.
d = VT + 0.5 AT^2
d = 12 rad/s * 5s + 0.5 * -1.2 rad/s^2 (5s)^2
d = 60 rad -0.6 rad/s^2 *25s^2
d = 60 rad -15 rad
d = 45 rad
So the top rotated 45 radians while decelerating from 12 rad/s to 6 rad/s</span>
Hi, time is independent variable. It's stands alone and isn't change by anything.
Temperature is dependant variable (depends on time)
Answer:
Explanation:
Given
mass of puck=166 gm
initial velocity=19.5 m/s
Final velocity=43.1 m/s at angle of 
to the intial direction
Suppose puck is travelling towards positive x axis
thus initial moment 
Final momentum 
Impusle
Angle between initial velocity and force
w.r.t x-axis
and Fdt=Impulse
