Zone between each team's blue line and goal line in ice hocky

1 answer:

3 0

Answer:Each goal line is 11 feet (3.4 m) from the end boards. NHL blue lines are 75 feet (22.9 m) from the end boards and 50 feet (15.2 m) apart.

Explanation:When the other team is on the attack, the defensive zone is the area between your goal line and your blue line. The central ice area between the two blue lines (neither the defending nor the attacking zone). When the your team is on the attack, the offensive zone is the area between blue line and your opponents goal.

Your friend, Tim, is playing with his sled. He ties a rope to his sled and attaches it to Lar's snowmobile. Tim has a mass of 71

kykrilka [37]

The maximum speed of Tim is 16.95 m/s.

The given parameters:

Mass of the rope, m = 71 kg
Tension on the rope, T = 220 N
Coefficient of kinetic friction, = 0.1
Time of motion, t = 8 s

<h3>What is Newton's second law of motion?</h3>

Newton's second law of motion states that, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

The net force on Tim is calculated by applying Newton's second law of motion as follows;

$T - \mu _k F_n = ma\\\\T - \mu _k F_n = m\frac{v}{t} \\\\T - \mu_k mg = m\frac{v}{t} \\\\t(\frac{T - \mu_k mg}{m} )= v\\\\8 (\frac{220 \ -\ 0.1 \times 71 \times 9.8}{71} ) =v \\\\ 16.95 \ m/s = v$

Thus, the maximum speed of Tim is 16.95 m/s.

A ramp with a mechanical advantage of 8 lifts objects to a height of 1.5 meters how long is the ramp

AlekseyPX

Given data:

M.A. = 8 (No units),

Ramp height (h)= 1.5 m, lifted,

Determine how long is the ramp=?

General formula 

 Mechanical Advantage = (Ramp length) ÷ (Ramp height),

 M.A = l ÷ h 

 8 × 1.5 = l = 12 m long

length of the ramp l ramp = 12 m

Record breaking low temperatures are associated with which air mass?

Papessa [141]

Answer:

Arctic Air masses

Explanation:

The Arctic Air masses are the world's most cold air masses. Specifically they are called Continental Arctic. Extremely cold and with very little moisture(extremely dry). These originate from north arctic region of 24 hour darkness that make the wind extremely cold and dry. The temperature in these regions are well below -50°C.

Answer:

(a) 20,154.1 J

(b) 95,223.5 J

Explanation:

The expression for the moment of inertia for the uniform solid cylinder is as follows;

$I= \frac{1}{2}mr^{2}$
