Answer: 25 m
Explanation:
The resolving power of a telescope is given by:
Diameter of the telescope = 10.0 m
Wavelength of the telescope = 550 nm = 550 ×10⁻⁹m
Thus, the resolving power of one of telescopes at the Keck Observatory is:
Also,
separation between objects = tan (3.85×10⁻⁶)° × 3.8×10⁵km = 2.5 × 10⁻²km =25 m
Answer:
If she is walking 30 feet every 10 seconds, that means she is walking 180 feet per minute. Multiply that by the 60 minutes in an hour, means she walks (180x60)= 10,800 feet an hour.
She walks 3 feet a second.
She walks 180 feet a minute.
She walks 10,800 feet an hour.
Explanation:
Answer:
The unit rate is $0.22 lb
Explanation:
The given parameters are;
The price for 18 lb = $3.99
We have;
The unit rate is the price for one unit. Whereby the unit of measurement is the lb, we have that one unit = 1 lb.
Therefore, given that 1 lb = 18 lb/18, the price of 1 lb which is the unit rate is given as follows;
18 lb price = $3.99
Divide both sides by 18 to get;
18 lb/18 = $3.99/18 = $0.221
Therefore, we have;
1 lb = 18 lb/18 = $0.221
The unit rate, which is the cost for 1 lb to the nearest hundredth = $0.22/lb.
Answer:
B
Explanation:
It will give the of 6 which is least of all the other forces.
4.0²+4.0² = c²
6 = c
Answer:
Δx = 30000002.4meters
Explanation:
First you transform km/h into m/s and minutes into seconds
so we have that 28000 km/h = 5555.556m/s
and 90min = 5400s
Then you take the formula for speed when the speed is uniform which is
u = Δx/Δt
5555.556 = Δx/5400
Solving for Δx=30000002.4meters.
