Answer:
Brahe showed irregularities in the Moon's orbit and discovered a new star in the Cassiopeia formation. Brahe invented many instruments such as the Tyconian Quadrant which were widely copied and led to the invention of improved observational equipment. In 1600, Tyco Brahe hired Johannes Kepler as his assistant.

Answer:
h = 5.05 m
Explanation:
given,
mass of pole vaulter, m = 64 Kg
speed of the vaulter,V = 10.2 m/s
horizontal component of velocity in air, v = 1 m/s
height of the jump,h = ?
using energy conservation
initial height of the vaulter is equal to zero.
h = 5.05 m
height of the jump is equal to 5.05 m.
Answer: In a battery, voltage determines how strongly electrons are pushed through a circuit, much like pressure determines how strongly water is pushed through a hose. Most AAA, AA, C, and D batteries are around 1.5 volts. Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours.
Explanation: Today "AA" is frequently used as a size designation, irrespective of the battery's electrochemical system. The main numbers used for the most common NiMH and NiCad battery
0.030 hours
First part of run
d = 1.5 km
s = 85 km/h
t = d / s = 1.5/85
t1 = 0.017647 hours
Second part of run
d = 0.80 km
s = 67 km/h
t = d / s = 0.80/67
t2 = 0.011940 hours
t1 + t2 = 0.017647 + 0.011940
= 0.030 â„Žours
Answer:
The magnitude of electric field is 
and the direction is inward.
Explanation:
Given that,
Length of rod = 10.0 cm
Charge
Distance D = (34.0-10) cm = 0.24 m
We need to calculate the electric field along the axis
Where, Q = charge
D = distance
Put the value into the formula
Negative sign shows the direction of electric field is inward that means toward the center.
Hence, The magnitude of electric field is and the direction is inward.
