Complete Question
Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?
Answer:
The time it would take at the given speed is 
Explanation:
From the question we are told that
The time taken to exist the highway is 
The distance to the exist is 
Alberta speed is 
The time it would take travelling at the given speed is mathematically represented as
substituting values
Converting to minutes
1 hour = 60 minutes
So 0.71667 hours = x minutes
Therefore
Answer:
0.5 Amperes
Explanation:
Information that we have:
Power: 
Voltage: 
and we use the equation that relates this two quantities to the Current (I):
where I is the curent, P is the Power and V is the Voltage.
we substitute the values given for the Power and the Voltage to find the current:
the Current running into the bulb is 0.5 Amperes
Answer:
25.2 cm
Explanation:
K = 1050 N/m
m = 1.95 kg
h = 1.75 m
By the conservation of energy, the potential energy of the block is converted into the potential energy stored in the spring
m g h = 1/2 x k x y^2
Where, y be the distance by which the spring is compressed.
1.95 x 9.8 x 1.75 = 1/2 x 1050 x y^2
33.44 = 525 x y^2
y = 0.252 m
y = 25.2 cm
Answer:
3 quarters of the world likes pizza. (75%) and the remaining quarter of people (25%) dont like pizza.
Explanation:
It's pressure become three times larger because according to Boyles Law the pressure of fixed mass of gas is inversely proportional to it's volume provided that temp remains constant. That means a reduction in volume, will result in an increase in pressure and vice versa.
