Glaciers shaped the landscape is the answer. Actually, in Nova Scotia near Halifax there is a glacial boulder or erratic of basalt which is deemed to come from about 130km away perhaps from the north or NW. Also, there are glacial striations there on the bedrock which can be used to determine the sense of the direction of flow of the ice. In New England, there are pro-glacial lakes. Both the Maritimes and New England were most likely covered by the Laurentide continental glaciation.

Are higher than average sea surface temperatures associated with a greater than average number of hurricanes each year? In a 201

Verdich [7]

Answer:

hello the options to your question is missing below are the options

A. number of hurricanes above or below average.

B. the global sea surface temperature anomaly.

C. the number of hurricanes used in the study.

D. None of the answer options is correct.

answer : number of hurricanes above or below average ( A)

Explanation:

The response variable is number of hurricanes Above or below , because from the response it can be deduced that what causes the temperature of the sea to be above the average sea temperature is the number of Hurricanes above the average number of hurricanes per year. hence the response variable is (The number of hurricanes above or below per year )

3. A space vehicle is traveling at 4300 km/h relative to Earth when the exhausted rocket motor (mass 4m) is disengaged and sent

kvv77 [185]

Answer: Vce= 4234.4km/hr or 1180m/s

Explanation:

Mass of rocket motor Mr= 4m

Mass of control module Mc= m

Initial velocity of spaceship relative to earth Vs= 4300km/hr

Final velocity of command module relative to the rocket motor Vrc = 82km/hr

Total mass of spaceship M= 4m+m= 5m

Using law of conservation of momentum;

MVs= MrVre + McVce eqn1

Vre = Vrc+Vce eqn2

Where Vce is velocity of control room relative to the earth and Vre is velocity of rocket motor relative to the earth

Substituting eqn2 to eqn1, we have.

MVs= Mr(Vrc+Vce) +McVce

MVs= MrVrc+MrVce+McVce

Making Vce the subject of formula.

Vce = (MVs-MrVrc)/(Mc+Mr)

Substituting the values we have,

Vce = (5m×4300km/hr - 4m×82km/hr)/ (m+4m)

Vce = 21172m/5m

Vce= 4234.4km/hr or 1180m/s
